RClamp0534N Low Capacitance TVS for High-Speed Interfaces PROTECTION PRODUCTS - RailClamp® Description Features ‹ ESD protection for high-speed data lines to RailClamp® TVS diodes are specifically designed to protect sensitive components which are connected to high-speed data and transmission lines from overvoltage caused by ESD (electrostatic discharge), CDE (cable discharge events), and EFT (electrical fast transients). The unique design incorporates surge rated, low capacitance steering diodes and a TVS diode in a single package. This allows the device to absorb large amounts of energy while protecting downstream components from harmful transient events. The RClamp®0534N is in a 10-pin SLP3020N10 package. It measures 3.0 x 2.0 x 0.60mm. The leads are finished with lead-free NiPdAu. The combination of small size, low capacitance, and high surge capability makes them ideal for use in applications such as 10/ 100 Ethernet, USB 2.0, and video interfaces. ‹ ‹ ‹ ‹ ‹ ‹ ‹ IEC 61000-4-2 (ESD) ±30kV (air), ±30kV (contact) IEC 61000-4-4 (EFT) 40A (5/50ns) IEC 61000-4-5 (Lightning) 25A (8/20μs) Array of surge rated diodes with internal TVS Diode Small package saves board space Protects four I/O lines and Voltage Bus Low capacitance: 5pF (VR=0V) Low clamping voltage Low operating voltage: 5.0V Solid-state silicon-avalanche technology Mechanical Characteristics ‹ ‹ ‹ ‹ ‹ ‹ ‹ SLP3020N10 10L package Pb-Free, Halogen Free, RoHS/WEEE Compliant Nominal Dimensions: 3.0 x 2.0 x 0.60 mm Lead Finish: NiPdAu Molding compound flammability rating: UL 94V-0 Marking : Marking code + Date code Packaging : Tape and Reel Applications ‹ ‹ ‹ ‹ ‹ ‹ Circuit Diagram USB 2.0 Power and Data Line Protection Video Graphics Cards Monitors and Flat Panel Displays Digital Video Interface (DVI) Notebook Computers Networking Equipment Circuit Diagram I/0 1 In 10 I/0 2 In 1 2 4 GND 5 3, 8, Tabs 1 VCC NC GND I/0 3 In NC I/0 4 In NC Pin Assignments (Top View) (Note tabs are connected to GND Pins) Revision 10/21/2010 1 www.semtech.com RClamp0534N PROTECTION PRODUCTS Absolute Maximum Rating R ating Symbol Value Units Peak Pulse Power (tp = 8/20μs) Pp k 500 Watts Peak Pulse Current (tp = 8/20μs) IP P 25 A ESD p er IEC 61000-4-2 (Air) ESD p er IEC 61000-4-2 (Contact) VESD +/- 30 +/- 30 kV TJ -55 to +125 °C TSTG -55 to +150 °C Op erating Temp erature Storage Temp erature Electrical Characteristics (T=25oC) Parameter Symbol Conditions Minimum Typical Maximum Units 5 V Reverse Stand-Off Voltage VRWM Reverse Breakdown Voltage V BR It = 1mA Reverse Leakage Current IR VRWM = 5V, T=25°C 0.5 μA Clamping Voltage VC IPP = 1A, tp = 8/20μs Any I/O to GN D 10 V Clamping Voltage VC IPP = 10A, tp = 8/20μs Any I/O to GN D 12 V Clamping Voltage VC IPP = 25A, tp = 8/20μs Any I/O to GN D 15 V Junction Capacitance Cj Any I/O to GN D VR = 0V, f = 1MHz 3.5 5 pF I/O to I/O VR = 0V, f = 1MHz 1.5 3 pF © 2010 Semtech Corp. 2 6 V www.semtech.com RClamp0534N PROTECTION PRODUCTS Typical Characteristics Non-Repetitive Peak Pulse Power vs. Pulse Time Power Derating Curve 10 110 % of Rated Power or PI P Peak Pulse Power - P PP (kW) 100 1 0.1 90 80 70 60 50 40 30 20 10 0 0.01 0.1 1 10 0 100 25 50 Pulse Duration - tp (s) 110 Percent of I PP 80 -t 50 40 150 14 Clamping Voltage -VC (V) 90 e 125 15 Waveform Parameters: tr = 8µs td = 20µs 100 60 100 Clamping Voltage vs. Peak Pulse Current Any I/O to GND (tp = 8/20us) Surge Current Output Waveform (tp = 8/20us) 70 75 Ambient Temperature - TA (oC) td = IPP/2 30 13 12 11 10 9 8 7 20 6 10 5 Waveform Parameters: tr = 8µs td = 20µs 4 0 0 5 10 15 20 25 0 30 5 10 15 20 25 30 Peak Pulse Current - IPP (A) Time (µs) Normalized Capacitance vs. Reverse Voltage Forward Voltage vs. Forward Current 12 2.00 1.80 10 Cj(VR) / Cj(VR=0V) Forward Voltage (V) 1.60 8 6 4 Waveform Parameters: tr = 8µs td = 20µs 2 1.40 1.20 1.00 0.80 0.60 0.40 0.20 f = 1 MHz 0.00 0 0 5 10 15 20 0 25 Peak Pulse Current (A) © 2010 Semtech Corp. 1 2 3 4 5 Reverse Voltage - VR (V) 3 www.semtech.com RClamp0534N PROTECTION PRODUCTS Typical Characteristics Insertion Loss S21 - Any I/O to GND CH1 S21 LOG Insertion Loss S21 - I/O to I/O 6 dB / REF 0 dB CH1 S21 LOG 6 dB / REF 0 dB 1: - 1.3256 dB 800 MHz 0 dB 5 3 -18 dB 2: - 1.6603 dB 900 MHz 0 dB 3: - 9.5266 dB 1.8 GHz -6 dB -12 dB 4 4: - 9.2059 dB 2.5 GHz -30 dB -30 dB -36 dB -36 dB -42 dB -42 dB 10 MHz 100 MHz START . 030 MHz -48 dB 3 1 GHz GHz STOP 3000. 000000 MHz 1 MHz 10 MHz 100 MHz START . 030 MHz ESD Clamping - Between any I/O and GND (+8kV Contact per IEC 61000-4-2) 3: - 3.8889 dB 1.8 GHz 4: - 10.034 dB 2.5 GHz 3 1 GHz GHz STOP 3000. 000000 MHz ESD Clamping - Between any I/O and GND (-8kV Contact per IEC 61000-4-2) Note: Data is taken with a 10x attenuator Note: Data is taken with a 10x attenuator © 2010 Semtech Corp. 4 -18 dB -24 dB 1 MHz 3 5 -24 dB -48 dB 2: - .65850 dB 900 MHz 12 12 -6 dB -12 dB 1: - .52910 dB 800 MHz 4 www.semtech.com RClamp0534N PROTECTION PRODUCTS Applications Information Figure 1- Pin Configuration (Top View) Device Connection Options for Protection of Four High-Speed Data Lines The RClamp0534N is designed to protect four data lines from transient over-voltages by clamping them to a fixed reference. When the voltage on the protected line exceeds the reference voltage (plus diode VF) the steering diodes are forward biased, conducting the transient current away from the sensitive circuitry. Data lines are connected at pins 1, 2, 4 and 5. The package is designed for easy trace routing. Pins 3 and 8 are internally connected to the center tabs and should be connected directly to a ground plane on the board for best results. The path length is kept as short as possible to minimize parasitic inductance. The positive reference (REF2) is connected at pin 9. The options for connecting the positive reference are as follows: I/0 1 In I/0 2 In GND 1. To protect data lines and the power line, connect pin 10 directly to the positive supply rail (VCC). In this configuration the data lines are referenced to the supply voltage. The internal TVS diode prevents over-voltage on the supply rail. 2. The RClamp0534N can be isolated from the power supply by adding a series resistor between pin 10 and VCC. A value of 100kΩ is recommended. The internal TVS and steering diodes remain biased, providing the advantage of lower capacitance. 3. In applications where no positive supply reference is available, or complete supply isolation is desired, the internal TVS may be used as the reference. In this case, pin 10 is not connected. The steering diodes will begin to conduct when the voltage on the protected line exceeds the working voltage of the TVS (plus one diode drop). © 2010 Semtech Corp. 1 VCC NC GND I/0 3 In NC I/0 4 In NC Figure 2 - Layout Example 5 www.semtech.com RClamp0534N PROTECTION PRODUCTS Outline Drawing - SLP3020N10 A D B DIMENSIONS DIM PIN 1 INDICATOR (LASER MARK) A A1 A2 b b1 D E e e1 e2 L L1 N aaa bbb E A SEATING PLANE aaa C C A1 A2 MILLIMETERS MIN NOM MAX 0.50 0.60 0.65 0.00 0.03 0.05 (0.15) 0.15 0.20 0.25 0.25 0.35 0.45 2.90 3.00 3.10 1.90 2.00 2.10 0.60 BSC 0.65 BSC 0.95 BSC 0.25 0.30 0.35 0.95 1.00 1.05 10 0.08 0.10 D/2 3X b1 1 2 LxN L1 /2 3X L1 E/2 N e bxN bbb C A B e1 e2 NOTES: 1.
