UL Recognized Component Description The TISP4360H3BJ is designed to limit overvoltages on equipment used for telephone lines carrying POTS (Plain Old Telephone System) and ADSL (Asymmetrical Digital Subscriber Line) signals. TISP4360H3BJ a.c. overload limits are specified for designers to select the correct overcurrent protectors to meet safety requirements, e.g. UL 1950. The protector consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping. If sufficient current is available from the overvoltage, the breakdown voltage will rise to the breakover level, which causes the device to switch into a low-voltage on-state condition. This switching action removes the high voltage stress from the following circuitry and causes the current resulting from the overvoltage to be safely diverted through the protector. The high holding (switch off) current prevents d.c. latchup as the diverted current subsides. The TISP4360H3BJ is guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. This high (H) current protection device is in a plastic SMBJ package (JEDEC DO-214AA with J-bend leads) and supplied in embossed carrier reel pack. For alternative voltage and holding current values, consult the factory.

They may be used either singly to limit the voltage between two conductors (Figure 11) or in multiples to limit the voltage at several points in a circuit (Figure 12). Th3 Th1 Th1 Th2 Figure 11. Two Point Protection Figure 12. Multi-point Protection In Figure 11, 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 12, 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 TISP4360H3BJ 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 Series resistance can be added to cover situations where either the TISP4360H3BJ current rating will be exceeded or excessive wiring currents result or both. When a primary protector is used, the TISP4360H3BJ may operate before the primary protector. With the TISP460H3BJ in a low voltage state, the primary protector is prevented from working. High currents, which should have been carried by the primary protector, now flow through the wiring to the equipment and through the TISP4360H3BJ. Interference and network equipment damage can occur, particularly if the currents are diverted to the local ground. Protector coordination prevents this problem. A series resistor can be used to develop a voltage drop large enough to activate the primary protector. If the primary protector was a gas discharge tube (GDT) with a maximum d.c. sparkover of 400 V and the typical lightning impulse decay time was several hundred microseconds (TISP4360H3BJ rating 200 A), a 2 Ω series resistor (400 V/200 A) would be sufficient to achieve coordination. At peak currents of 200 A and above, the resistor would develop at least 400 V and GDT would switch and divert the current.

Customers should verify actual device performance in their specific applications. TISP4360H3BJ Overvoltage Protector Series APPLICATIONS INFORMATION Impulse Testing (continued) 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 10, the appropriate series resistor value can be calculated for ambient temperatures in the range of -40 °C to 85 °C. AC Testing The protector can withstand currents applied for times not exceeding those shown in Figure 7. 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 from opening during impulse testing. The current versus time characteristic of the overcurrent protector must be below the line shown in Figure 7. In some cases, there may be a further time limit imposed by the test standard (e.g. UL 1459/1950 wiring simulator failure). Safety tests require that the equipment fails without any hazard to the user. For the equipment protector, this condition usually means that the fault mode is short circuit, ensuring that the following circuitry is not exposed to high voltages. The ratings table and Figure 8 detail the earliest times when a shorted condition could occur. Figure 8 shows how the protector current levels compare to UL 1950 levels. Only the UL 1950 600 V tests (1, 2 and 3) are shown, as these have sufficient voltage to operate the protector. Tests 4 (
