The TISP4xxxH3LM is available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used. These protectors have been specified mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The TISP4350H3LM meets the FCC Part 68 “B” ringer voltage requirement and survives the Type A and B impulse tests. These devices are housed in a through-hole DO-92 package (TO-92 package with cropped center leg).

Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is typically used for the protection of 2-wire telecommunication equipment (e.g. between the Ring and Tip wires for telephones and modems). Combinations of devices can be used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground). The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state causes the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current helps prevent d.c. latchup as the diverted current subsides.

They may be used either singly to limit the voltage between two conductors (Figure 12) or in multiples to limit the voltage at several points in a circuit (Figure 13). Th3 Th1 Th1 Th2 E T E L O S B O Figure 12. Two Point Protection Figure 13. Multi-point Protection In Figure 12, protector Th1 limits the maximum voltage between the two conductors to ±V(BO). This configuration is normally used to protect circuits without a ground reference, such as modems. In Figure 13, protectors Th2 and Th3 limit the maximum voltage between each conductor and ground to the ±V(BO) of the individual protector. Protector Th1 limits the maximum voltage between the two conductors to its ±V(BO) value. If the equipment being protected has all its vulnerable components connected between the conductors and ground, then protector Th1 is not required. Impulse Testing To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms. The table below shows some common values. Standard Peak Voltage Setting V Voltage Waveform µs 2/10 10/1000 10/160 10/560 9/720 † 9/720 † 0.5/700 Peak Current Value A Current Waveform µs TISP4xxxH3 25 °C Rating A Series Resistance Ω 2500 500 2/10 500 0 1000 100 10/1000 100 1500 200 10/160 250 0 800 100 10/560 160 0 FCC Part 68 (March 1998) 1500 37.5 5/320 † 200 0 1000 25 5/320 † 200 0 I3124 1500 37.5 0.2/310 200 0 37.5 1500 5/310 200 0 ITU-T K.20/K 21 10/700 100 4000 † FCC Part 68 terminology for the waveforms produced by the ITU-T recommendation K.21 10/700 impulse generator GR-1089-CORE If the impulse generator current exceeds the protector’s current rating, then a series resistance can be used to reduce the current to the protector’s rated value to prevent possible failure. The required value of series resistance for a given waveform is given by the following calculations. First, the minimum total circuit impedance is found by dividing the impulse generator’s peak voltage by the protector’s rated current. The impulse generator’s fictive impedance (generator’s peak voltage divided by peak short circuit current) is then subtracted from the minimum total circuit impedance to give the required value of series resistance. In some cases, the equipment will require verification over a temperature range. By using the rated waveform values from Figure 11, the appropriate series resistor value can be calculated for ambient temperatures in the range of -40 °C to 85 °C. AC Power Testing The protector can withstand currents applied for times not exceeding those shown in Figure 8. Currents that exceed these times must be terminated or reduced to avoid protector failure. Fuses, PTC (Positive Temperature Coefficient) resistors and fusible resistors are overcurrent protection devices which can be used to reduce the current flow. Protective fuses may range from a few hundred milliamperes to one ampere. In some cases, it may be necessary to add some extra series resistance to prevent the fuse opening during impulse testing. The current versus time characteristic of the overcurrent protector must be below the line shown in Figure 8. In some cases, there may be a further time limit imposed by the test standard (e.g. UL 1459 wiring simulator failure).

Customers should verify actual device performance in their specific applications. TISP4xxxH3LM Overvoltage Protector Series APPLICATIONS INFORMATION Capacitance The protector characteristic off-state capacitance values are given for d.c. bias voltage, VD, values of 0, -1 V, -2 V and -50 V. Where possible, values are also given for -100 V. Values for other voltages may be calculated by multiplying the VD = 0 capacitance value by the factor given in Figure 6. Up to 10 MHz, the capacitance is essentially independent of frequency. Above 10 MHz, the effective capacitance is strongly dependent on connection inductance. In many applications, such as Figure 15 and Figure 17, the typical conductor bias voltages will be about -2 V and -50 V. Figure 7 shows the differential (line unbalance) capacitance caused by biasing one protector at -2 V and the other at -50 V. Normal System Voltage Levels E T E L O S B O The protector should not clip or limit the voltages that occur in normal system operation. For unusual conditions, such as ringing without the line connected, some degree of clipping is permissible. Under this condition, about 10 V of clipping is normally possible without activating the ring trip circuit. Figure 10 allows the calculation of the protector VDRM value at temperatures below 25 °C. The calculated value should not be less than the maximum normal system voltages. The TISP4260H3LM, with a VDRM of 200 V, can be used for the protection of ring generators producing 100 V rms of ring on a battery voltage of -58 V (Th2 and Th3 in Figure 17). The peak ring voltage will be 58 + 1.414*100 = 199.4 V. However, this is the open circuit voltage and the connection of the line and its equipment will reduce the peak voltage. In the extreme case of an unconnected line, clipping the peak voltage to 190 V should not activate the ring trip. This level of clipping would occur at the temperature when the VDRM has reduced to 190/200 = 0.95 of its 25 °C value. Figure 10 shows that this condition will occur at an ambient temperature of -28 °C. In this example, the TISP4260M3LM will allow normal equipment operation provided that the minimum expected ambient temperature does not fall below -28 °C. JESD51 Thermal Measurement Method To standardize thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51 standard. Part 2 of the standard (JESD51-2, 1995) describes the test environment. This is a 0.0283 m3 (1 ft3) cube which contains the test PCB (Printed Circuit Board) horizontally mounted at the center. Part 3 of the standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one for packages smaller than 27 mm (1.06 ’’) on a side and the other for packages up to 48 mm (1.89 ’’). The LM package measurements used the smaller 76.2 mm x 114.3 mm (3.0 ’’ x 4.5 ’’) PCB. The JESD51-3 PCBs are designed to have low effective thermal conductivity (high thermal resistance) and represent a worse case condition. The PCBs used in the majority of applications will achieve lower values of thermal resistance and so can dissipate higher power levels than indicated by the JESD51 values.
