These devices consist of a bidirectional suppressor element connecting the A and B terminals. They will suppress inter-wire voltage transients. Transients are initially clipped by zener action until the voltage rises to the breakover level, which causes the device to crowbar. The high crowbar holding current prevents d.c. latchup as the transient subsides. PRODUCT These monolithic protection devices are fabricated in ion-implanted planar structures to ensure precise and matched breakover control and are virtually transparent to the system in normal operation. INFORMATION Information is current as of publication date. Products conform to specifications in accordance with the terms of Power Innovations standard warranty. Production processing does not necessarily include testing of all parameters. 1 TISP4240LP SYMMETRICAL TRANSIENT VOLTAGE SUPPRESSORS MARCH 1997 - REVISED SEPTEMBER 1997 absolute maximum ratings at 25°C case temperature (unless otherwise noted)) RATING SYMBOL Non-repetitive peak on-state pulse current (see Notes 1, 2 and 3) 5/310 µs (CCITT IX K17, open-circuit voltage wave shape 1.5 kV, 10/700 µs) VALUE ITSP UNIT A 38 Non-repetitive peak on-state current, 50 Hz, 1 s (see Notes 1 and 2) ITSM 2.5 A rms Initial rate of rise of on-state current, diT/dt 250 A/µs TJ 150 °C 0 to 70 °C Linear current ramp, Maximum ramp value < 38 A Junction temperature Operating free - air temperature range Storage temperature range Tstg -40 to +150 °C Lead temperature 1.5 mm from case for 10 s Tlead 260 °C NOTES: 1. Above 70°C, derate linearly to zero at 150°C case temperature 2. This value applies when the initial case temperature is at (or below) 70°C. The surge may be repeated after the device has returned to thermal equilibrium. 3. Most PTT’s quote an unloaded voltage waveform. In operation the TISP essentially shorts the generator output.
