MD4XAB q device symbol q UL Recognized, E132482 description The TISP4082 is designed specifically for telephone equipment protection against lightning and transients induced by a.c. power lines. 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. 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. PRODUCT 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 TISP4082 SYMMETRICAL TRANSIENT VOLTAGE SUPPRESSORS APRIL 1987 - REVISED SEPTEMBER 1997 absolute maximum ratings at 25C case temperature (unless otherwise noted) RATING Non-repetitive peak on-state pulse current (see Notes 1, 2 and 3) 8/20 s (ANSI C62.41, open-circuit voltage wave shape 1.2/50 s) 10/160 s (FCC Part 68, open-circuit voltage wave shape 10/160 s) 5/200 s (VDE 0433, open-circuit voltage wave shape 2 kV, 10/700 s) 0.2/310 s (RLM 88, open-circuit voltage wave shape 1.5 kV, 0.5/700 s) 5/310 s (CCITT IX K17/K20, open-circuit voltage wave shape 2 kV, 10/700 s) 5/310 s (FTZ R12, open-circuit voltage wave shape 2 kV, 10/700 s) 10/560 s (FCC Part 68, open-circuit voltage wave shape 10/560 s) 10/1000 s (REA PE-60, open-circuit voltage wave shape 10/1000 s) Non-repetitive peak on-state current, 50 Hz, 2.5 s (see Notes 1 and 2) Initial rate of rise of on-state current, Junction temperature Operating free - air temperature range Storage temperature range Lead temperature 1.5 mm from case for 10 s Tstg Tlead Linear current ramp, Maximum ramp value < 38 A ITSM diT/dt TJ ITSP 150 60 50 38 50 50 45 40 10 250 150 0 to 70 -40 to +150 260 A rms A/s C C C C A SYMBOL VALUE UNIT NOTES: 1. Above 70C, derate linearly to zero at 150C case temperature 2. This value applies when the initial case temperature is at (or below) 70C. 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. The resulting loaded current waveform is specified. . electrical characteristics, TJ = 25C PARAMETER VZ VZ Reference zener voltage Temperature coefficient of reference voltage Breakover voltage Breakover current Peak on-state voltage Holding current Critical rate of rise of off-state voltage Off-state leakage current Off-state capacitance (see Notes 4 and 5) (see Note 4) IT = 5 A (see Note 4) (see Note 6) VD = 50 V VD = 0 f = 1 kHz 110 (see Notes 4 and 5) 150 5 10 200 0.15 2.2 IZ = 1mA TEST CONDITIONS MIN 58 0.1 82 0.6 3 TYP MAX UNIT V %/oC V A V mA kV/s A pF V(BO) I(BO) VTM IH dv/dt ID Coff NOTES: 4.
