Licensed  ISO** 9001 and ISO 14001 certified manufacturing facilities Description The 170A Digital TeraDLynxTM power modules are non-isolated dc-dc converters that can deliver up to 170A of output current. These modules operate over a 7 to 14Vdc input range and provide a precisely regulated output voltage from 0.1 to 1.5Vdc. The output voltage is programmable via an external resistor and/or PMBus control. Features include a digital interface using the PMBus protocol, remote On/Off, adjustable output voltage, Power Good signal and overcurrent, overvoltage and overtemperature protection. The PMBus interface supports a range of commands to both control and monitor the module. The module also includes a real time compensation loop that allows optimizing the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area. * UL is a registered trademark of Underwriters Laboratories, Inc. † CSA is a registered trademark of Canadian Standards Association.

Page 11 GE Preliminary Data Sheet 170A TeraDLynxTM: Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current Design Considerations performance of the module can be achieved by using the Tunable LoopTM feature described later in this data sheet. Input Filtering 10 To minimize input voltage ripple, ceramic capacitors are recommended at the input of the module. Figure 31 shows the input ripple voltage for various output voltages at 170A of load current with 4x470 + 12x22 + 12x4.7 µF and 2x470 + 6x22 + 12x4.7 µF input capacitor combinations. 30 4x470 + 12x47 +12x10 uF 8 6 4 2 0 4x470 + 12x22 + 12x4.7 uF 0.5 2x470 + 6x22 + 12x4.7 uF Ripple (mVp-p) 10x470 + 12x47 +12x10 uF Ripple (mVp-p) The 170A TeraDLynxTM module should be connected to a low ac-impedance source. A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pins of the module, to minimize input ripple voltage and ensure module stability. 0.7 0.9 1.1 1.3 1.5 Output Voltage(Volts) 25 Figure 32. Peak to peak output ripple voltage for various output voltages with external capacitors at the output (170A load). Input voltage is 12V. 20 Safety Considerations 15 10 0.5 0.7 0.9 1.1 1.3 1.5 For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1 2nd, CSA C22.2 No. 60950-1-07, DIN EN 609501:2006 + A11 (VDE0805 Teil 1 + A11):2009-11; EN 609501:2006 + A11:2009-03. Output Voltage(Volts) Figure 31. Input ripple voltage for various output voltages with two input capacitor combinations at 170A load. Input voltage is 12V. Output Filtering These modules are designed for low output ripple voltage and will meet the maximum output ripple specification with minimum of 12 x 22 µF ceramic capacitors at the output of the module. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a slow-blow fuse. When the input voltage is ≤ 8V, the recommendation is to use two 25A Littelfuse 456 series or equivalent fuses in parallel. For input voltages > 8V, a single 40A Littelfuse series 456 or equivalent fuse is recommended. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR polymer and ceramic capacitors are recommended to improve the dynamic response of the module. Figure 32 provides output ripple information for capacitance of ~3574µF (47µF (1210 ceramic) x 12 + 10µF (0805 ceramic) + 0.1uF (0402) x4 + 1000µF (polymer) x 3) at various Vo and a full load current of 170A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table.

Page 12 GE Preliminary Data Sheet 170A TeraDLynxTM: Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current Analog Feature Descriptions The trim resistor is only determined during module initialization and hence cannot be used for dynamic output voltage adjustment Remote On/Off The TeraDLynx 170A module can be turned ON and OFF either by using the ON/OFF pin (Analog interface) or through the PMBus interface (Digital). The module can be configured in a number of ways through the PMBus interface to react to the ON/OFF input:    Module ON/OFF can controlled only through the analog interface (digital interface ON/OFF commands are ignored) Module ON/OFF can controlled only through the PMBus interface (analog interface is ignored) Module ON/OFF can be controlled by either the analog or digital interface The default state of the module (as shipped from the factory) is to be controlled by the analog interface only. If the digital interface is to be enabled, or the module is to be controlled only through the digital interface, this change must be made through the PMBus. These changes can be made and written to non-volatile memory on the module so that it is remembered for subsequent use. Analog On/Off The 170A Digital TeraDLynxTM power modules feature an On/Off pin for remote On/Off operation. With the Negative Logic On/Off option, (see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal should be always referenced to ground. Leaving the On/Off pin disconnected will turn the module ON when input voltage is present. With the positive logic on/off option, the module turns ON during logic high and OFF during logic low. Digital On/Off Please see the Digital Feature Descriptions section. Monotonic Start-up and Shutdown The module has monotonic start-up and shutdown behavior on the output for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output The module will start into a pre biased output on output as long as the pre bias voltage is 0.5V less than the set output voltage. Analog Output Voltage Programming The output voltage of the module is programmable to any voltage from 0.1 to 1.5Vdc, as shown in Table 1, by connecting a resistor between the Trim and SIG_GND pins of the module as shown in Fig 33. Without an external resistor between the Trim pin and SIG_GND pins, the output of the module will be 0.1 Vdc. The value of the trim resistor, RTrim for a desired output voltage, should be selected as shown in Table 1. January 3, 2017 RTRIM RTRIM SIG_GND Figure 33.

Digital Output Voltage Margining Digital Adjustable Overcurrent Warning Please see the Digital Feature Descriptions section. Please see the Digital Feature Descriptions section. Output Voltage Sequencing Overtemperature Protection The power module includes a sequencing feature, EZSEQUENCE that enables users to implement various types of output voltage sequencing in their applications. This is accomplished via an additional sequencing pin. When not using the sequencing feature, leave it unconnected. To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 135 °C (typ) is exceeded at the thermal reference point Tref. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart.

SEQ Digitally Adjustable Output Over and Under Voltage Protection SIG_GND Please see the Digital Feature Descriptions section. SIG_GND Figure 34. Circuit showing connection of the sequencing signal to the SEQ pin. When the sequencing voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches the set-point voltage. The final value of the sequencing voltage must be set higher than the set-point voltage of the module. The output voltage follows the sequencing voltage on a one-to-one basis. By connecting multiple modules together, multiple modules can track their output voltages to the voltage applied on the SEQ pin. The module’s output can track the SEQ pin signal with slopes of up to 0.5V/msec during power-up or power-down. To initiate simultaneous shutdown of the modules, the SEQ pin voltage is lowered in a controlled manner. The output voltage of the modules tracks the voltages below their setpoint voltages on a one-to-one basis. A valid input voltage must be maintained until the tracking and output voltages reach ground potential. Digital Sequencing The module can support digital sequencing by allowing control of the turn-on delay and rise times as well as turnoff and fall times, Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, module operation for the associated output is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Digitally Adjustable Input Undervoltage Lockout Please see the Digital Feature Descriptions section. Digitally Adjustable Power Good Thresholds Please see the Digital Feature Descriptions section. Synchronization The module switching frequency is capable of being synchronized to an external signal frequency within a specified range. Synchronization is done by using the external signal applied to the SYNC pin of the module as shown in Fig. 35, with the converter being synchronized by the rising edge of the external signal. The Electrical Specifications table specifies the requirements of the external SYNC signal. If the SYNC pin is not used, the module should free run at the default switching frequency. MODULE Digital Output Voltage Margining SYNC Please see the Digital Feature Descriptions section. + Overcurrent Protection (OCP) To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry on output and can endure current limiting continuously. The module overcurrent response is non-latching shutdown with automatic recovery. OCP response time is programmable through manufacturer specific commands. The unit January 3, 2017 ─ GND Figure 35.

Digital Compensator The TJT170 module uses digital control to regulate the output voltage. As with all POL modules, external capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. The TJT170 comes with default compensation values programmed into the non-volatile memory of the module. These digital compensation values can be adjusted externally to optimize transient response and also ensure stability for a wide range of external capacitance, as well as with different types of output capacitance. This can be done by two different methods. 1. By allowing the user to select among several pre-tuned compensation choices to select the one most suited to the transient response needs of the load. This selection is made via a resistor RTune connected between the RTUNE and SIG_GND pins as shown in Fig. 35. Table 2 shows various pre-tuned compensation combinations recommended for various external capacitor combinations. 2. Using PMBus to change compensation parameters in the module. Note that during initial startup of the module, compensation values that are stored in non-volatile memory are used. If a resistor RTune is connected to the module, then the compensation values are changed to ones that correspond to the value of RTUNE. If RTUNE is open however, no change in compensation values is made. Finally, if the user chooses to do so, they can overwrite the compensation values via PMBus commands.  COMP1: Recommended for the case where all of the output capacitance is composed of only ceramic capacitors. The range of external output capacitance is from 1470 µF to a maximum value of 17640 µF)  COMP2: For the most commonly used mix of ceramic and polymer type capacitors that have higher output capacitance in a smaller size. The range of output capacitance is from 2564 µF to a maximum of 30564 uF. This is the combination of output capacitance and compensation that can achieve the best transient response at lowest cost and smallest size. For example, with the maximum output capacitance of 12 x 47µF ceramics + 25 x 1000 µF polymer capacitors, and selecting RTUNE = 5.36kΩ, transient deviation can be as low as 25 mV, for a 50% load step (0 to 85A).  COMP3: Suitable for a mix of ceramic and higher ESR polymers or electrolytic capacitors, with output capacitance ranging from a minimum of 2204 µF to a maximum of 30084 µF. Selecting RTUNE according to Table 2 will ensure stable operation of the module with sufficient stability margin as well as yield optimal transient response. In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 3 lists recommended values of RTUNE in order to meet 2% output voltage deviation limits for some common output voltages in the presence of an 85A to 170A step change (50% of full load), with an input voltage of 12V. Please contact your GE technical representative to obtain more details of this feature as well as for guidelines on how to select the right value of external RTUNE to tune the module for best transient performance and stable operation for other output capacitance values. Simulation models are also available via the GE Power Module Wizard to predict stability characteristics and transient response. RTUNE Recommended values of RTUNE for different output capacitor combinations are given in Table 2. If no RTUNE is used, the default compensation values are used. The TJT170 pre-tuned compensation can be divided into three different banks (COMP1, COMP2, COMP3) that are available to the user to compensate the control loop for various values and combinations of output capacitance and to obtain reliable and stable performance under different conditions. Each bank consists of 20 different sets of compensation coefficients pre-calculated for different values of output capacitance. The three banks are set up as follows: January 3, 2017 RTUNE SIG_GND Figure 36. Circuit diagram showing connection of RTUNE to tune the control loop of the module. ©2017 General Electric Company.

Page 17 GE Preliminary Data Sheet 170A TeraDLynxTM: Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current Digital Feature Descriptions The value is of the number is then given by Value = Mantissa x 2 Exponent PMBus Interface Capability PMBus Addressing The 170A TeraDLynx power modules have a PMBus interface that supports both communication and control. The PMBus Power Management Protocol Specification can be obtained from www.pmbus.org. The modules support a subset of version 1.1 of the specification (see Table 4 for a list of the specific commands supported). Most module parameters can be programmed using PMBus and stored as defaults for later use. Communication over the module PMBus interface supports the Packet Error Checking (PEC) scheme. The PMBus master must generate the correct PEC byte for all transactions, and check the PEC byte returned by the module. The power module is addressed through the PMBus using a device address. The module supports 128 possible addresses (0 to 127 in decimal) which can be set using resistors connected from the ADDR0 and ADDR1 pins to SIG_GND. Note that some of these addresses (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 12, 40, 44, 45, 55 in decimal) are reserved according to the SMBus specification and may not be useable. The address is set in the form of two octal (0 to 7) digits, with each pin setting one digit. The ADDR1 pin sets the high order digit and ADDR0 sets the low order digit. The resistor values suggested for each digit are shown in Table 3 (E96 series resistors are recommended). Note that if either address resistor value is outside the range specified in Table 4, the module will respond to address 127. The user must know which I2C addresses are reserved in a system for special functions and set the address of the module to avoid interfering with other system operations. Both 100kHz and 400kHz bus speeds are supported by the module. Connection for the PMBus interface should follow the High Power DC specifications given in section 3.1.3 in the SMBus specification V2.0 for the 400kHz bus speed or the The module also supports the SMBALERT# response protocol whereby the module can alert the bus master if it wants to talk. For more information on the SMBus alert response protocol, see the System Management Bus (SMBus) specification. The module has non-volatile memory that is used to store configuration settings. Not all settings programmed into the device are automatically saved into this non-volatile memory, only those specifically identified as capable of being stored can be saved (see Table 4 for which command parameters can be saved to non-volatile storage). Low Power DC specifications in section 3.1.2. The complete SMBus specification is available from the SMBus web site, smbus.org. PMBus Data Format For commands that set thresholds, voltages or report such quantities, the module supports the “Linear” data format among the three data formats supported by PMBus. The Linear Data Format is a two-byte value with an 11-bit, two’s complement mantissa and a 5-bit, two’s complement exponent.

Page 18 GE Preliminary Data Sheet 170A TeraDLynxTM: Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current Operation (01h) This is a paged register. The OPERATION command can be used to turn the module on or off in conjunction with the ON/OFF pin input. It is also used to margin up or margin down the output voltage PMBus Enabled On/Off The module can also be turned on and off via the PMBus interface. The OPERATION command is used to actually turn the module on and off via the PMBus, while the ON_OFF_CONFIG command configures the combination of analog ON/OFF pin input and PMBus commands needed to turn the module on and off. Bit [7] in the OPERATION command data byte enables the module, with the following functions: 0 1 : : Output is disabled Output is enabled This module uses the lower five bits of the ON_OFF_CONFIG data byte to set various ON/OFF options as follows: Bit Position Access Function Default Value 4 r/w PU 1 3 r/w CMD 0 2 r/w CPR 1 1 r POL x 0 r CPA 1 PU: Sets the default to either operate any time input power is present or for the ON/OFF to be controlled by the analog ON/OFF input and the PMBus OPERATION command. This bit is used together with the CP, CMD and ON bits to determine startup. Bit Value 0 1 Action Module powers up any time power is present regardless of state of the analog ON/OFF pin Module does not power up until commanded by the analog ON/OFF pin and the OPERATION command as programmed in bits [2:0] of the ON_OFF_CONFIG register. CMD: The CMD bit controls how the device responds to the OPERATION command. Bit Value 0 1 Action Module ignores the ON bit in the OPERATION command Module responds to the ON bit in the OPERATION command CPR: Sets the response of the analog ON/OFF pin. This bit is used together with the CMD, PU and ON bits to determine startup. Bit Value 0 1 Action Module ignores the analog ON/OFF pin, i.e. ON/OFF is only controlled through the PMBUS via the OPERATION command Module requires the analog ON/OFF pin to be asserted to start the unit January 3, 2017 CPA: Sets the action of the analog ON/OFF pin when turning the controller OFF. This bit is internally read and cannot be modified by the user PMBus Adjustable Soft Start Rise Time The soft start rise time of module output is adjustable in the module via PMBus. The TON_RISE command can set the rise time in ms, and allows choosing soft start times between 0 and 1000ms. Output Voltage Adjustment Using the PMBus Two PMBus commands are available to change the output voltage setting. The first, VOUT_COMMAND can set the output voltage directly. The second, VOUT_TRIM is used to apply an offset to the commanded output voltage. Since the output voltage can be set using an external RTrim resistor as well, an additional PMBus command MFR_VOUT_SET_MODE is used to tell the module whether the VOUT_COMMAND is used to directly set output voltage or whether RTrim is to be used. If MFR_VOUT_SET_MODE is set to where bit position 7 is set at 1, then VOUT_COMMAND is ignored and output voltage is set solely by RTrim. If bit 7 of MFR_VOUT_SET_MODE is set to 0, then output voltage is set using VOUT_COMMAND, and the value of RTrim is only used at startup to set the output voltage. The second output voltage adjustment command VOUT_TRIM works in either case to provide a fixed offset to the output voltage. This allows PMBus adjustment of the output voltage irrespective of how MFR_VOUT_SET_MODE is set and allows digital adjustment of the output voltage setting even when RTrim is used. For all digital commands used to set or adjust the output voltage via PMBus, the resolution is 98µV. Output Voltage Margining Using the PMBus The output voltage of the module can be margined via PMBus between 0 and 1.5V. The margining voltage can be adjusted in 98µV steps. PMBus Adjustable Overcurrent Warning The module can provide an overcurrent warning via the PMBus. The threshold for the overcurrent warning can be set using the parameter IOUT_OC_WARN_LIMIT. This command uses the “Linear” data format with a two byte data word where the upper five bits [7:3] of the high byte represent the exponent and the remaining three bits of the high byte [2:0] and the eight bits in the low byte represent the mantissa. The value of the IOUT_OC_WARN_LIMIT can be stored to non-volatile memory using the STORE_DEFAULT_ALL command. Temperature Status via PMBus The module provides information related to temperature of the module through standardized PMBus commands. Commands READ_TEMPERATURE1, READ_TEMPERATURE_2 are mapped to module temperature and internal temperature of the PWM controller, respectively. The temperature readings are returned in °C and in two bytes. ©2017 General Electric Company. All rights reserved.

The PMBus command VOUT_OV_FAULT_LIMIT is used to set the output over voltage threshold. The default value is configured to be 112.5% of the commanded output. The command VOUT_UV_FAULT_LIMIT sets the threshold that detects an output under voltage fault. The default values are 87.5% of the commanded output voltage. Both commands use two data bytes formatted in the Linear format. PMBus Adjustable Input Undervoltage Lockout The module allows adjustment of the input under voltage lockout and hysteresis. The command VIN_ON allows setting the input voltage turn on threshold, while the VIN_OFF command sets the input voltage turn off threshold. For the VIN_ON command possible values are 7 to 14V and for the VIN_OFF command, possible values are 6.75V to 14V . Both VIN_ON and VIN_OFF commands use the “Linear” format with two data bytes. Measurement of Output Current, Output Voltage and Input Voltage The module can measure key module parameters such as output current, output voltage and input voltage and provide this information through the PMBus interface. Measuring Output Current Using the PMBus The module measures output current by using a signal derived from the switching FET currents. The current gain factor is accessed using the IOUT_CAL_GAIN command, and consists of two bytes in the Linear data format. During manufacture, each module is calibrated by measuring and storing the current gain factor into non-volatile storage. The current measurement accuracy is also improved by each module being calibrated during manufacture with the offset in the current reading. The IOUT_CAL_OFFSET command is used to store and read the current offset. The READ_IOUT command provides module average output current information. This command only supports positive output current, i.e. current sourced from the module. If the converter is sinking current a reading of 0 is provided. The READ_IOUT command returns two bytes of data in the Linear data format. Measuring Output Voltage Using the PMBus The module provides output voltage information using the READ_VOUT command. The command returns two bytes of data in Linear format. Measuring Input Voltage Using the PMBus The module provides input voltage information using the READ_VIN command. The command returns two bytes of data in the Linear format. January 3, 2017 Reading the Status of the Module using the PMBus The module supports a number of status information commands implemented in PMBus.

On startup, the module uses stored values of the four compensation parameters KD, KI, KP and ALPHA. If the module detects a valid value of RTUNE connected to the module, the values of KD, KI, KP and ALPHA are then changed to the appropriate values. Beyond this, the user can use the PMBus commands listed below to overwrite the values of KD, KP, KI and ALPHA. MFR_SPECIFIC_KP: Allows the user to program the value of the KP compensation coefficient. The allowed range is 32768 to 32767. The entire 16 bits are used to enter this range of integer values in two’s complement binary format. MFR_SPECIFIC_KI: Allows the user to program the value of the KI compensation coefficient. The allowed range is 32768 to 32767. The entire 16 bits are used to enter this range of integer values in two’s complement binary format.

The entire 16 bits are used to enter this range of integer values in two’s complement binary format. MFR_SPECIFIC_ALPHA: Allows the user to program the value of the ALPHA compensation coefficient. The allowed range is -256 to 256. The entire 16 bits are used to enter this range of integer values in two’s complement binary format. MFR_SPECIFIC_00: Returns information related to the type of module and revision number. Bits [7:2] in the Low Byte indicate the module type (001110 corresponds to the TJT170 series of module), while bits [7:3] in the high byte indicate the revision number of the module.

Page 33 GE Preliminary Data Sheet 170A TeraDLynxTM: Non-Isolated DC-DC Power Modules 7Vdc –14Vdc input; 0.1Vdc to 1.5Vdc output; 170A Output Current Thermal Considerations Power modules operate in a variety of thermal environments; however, sufficient cooling should always be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. The test set-up is shown in Figure 37. The preferred airflow direction for the module is in Figure 38. 25.4_ (1.0) Wind Tunnel PWBs Power Module Figure 38. Preferred airflow direction and location of hotspots of the module (Tref). 76.2_ (3.0) x 12.7_ (0.50) Probe Location for measuring airflow and ambient temperature Air flow The thermal reference points, Tref used in the specifications are also shown in Figure 38. For reliable operation the temperatures at these points should not exceed 120°C. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board-Mounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures.

Nozzle Recommendations The module weight has been kept to a minimum by using open frame construction. Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended inside nozzle diameter for reliable operation is 15mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 22 mm. Figure 39. Recommended linear reflow profile using Sn/Ag/Cu solder. Bottom Side / First Side Assembly Post Solder Cleaning and Drying Considerations This module is not recommended for assembly on the bottom side of a customer board. If such an assembly is attempted, components may fall off the module during the second reflow process. Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04-001). Lead Free Soldering The modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability. Pb-free Reflow Profile Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 40. Soldering outside of the recommended profile requires testing to verify results and performance. MSL Rating The 170A TeraDLynxTM modules have a MSL rating of 3. Storage and Handling The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at January 3, 2017 ©2017 General Electric Company.
