These devices will supress voltage transients between terminals A and C, B and C, and A and B. Negative 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. Positive transients are clipped by diode action. 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 TISP1082L DUAL ASYMMETRICAL TRANSIENT VOLTAGE SUPPRESSORS FEBRUARY 1990 - REVISED SEPTEMBER 1997 absolute maximum ratings at 25°C case temperature (unless otherwise noted) RATING SYMBOL VALUE UNIT Non-repetitive peak on-state pulse current (see Notes 1, 2 and 3) 8/20 µs (ANSI C62.41, open-circuit voltage wave shape 1.2/50 µs) 150 10/160 µs (FCC Part 68, open-circuit voltage wave shape 10/160 µs) 60 5/200 µs (VDE 0433, open-circuit voltage wave shape 2 kV, 10/700 µs) 50 ITSP 0.2/310 µs (RLM 88, open-circuit voltage wave shape1.5 kV, 0.5/700 µs) A 38 5/310 µs (CCITT IX K17/K20, open-circuit voltage wave shape 2 kV, 10/700 µs) 50 5/310 µs (FTZ R12, open-circuit voltage wave shape 2 kV, 10/700 µs) 50 10/560 µs (FCC Part 68, open-circuit voltage wave shape 10/560 µs) 45 10/1000 µs (REA PE-60, open-circuit voltage wave shape 10/1000 µs) 50 Non-repetitive peak on-state current, 50 Hz, 0.7 s (see Notes 1 and 2) ITSM 10 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.
