description
The TISP3082L is designed specifically for telephone equipment protection against lightning and transients induced by a.c. power lines. These devices consist of two bidirectional suppressor elements connected to a Common (C) terminal. These devices will supress voltage transients between terminals A and C, B and C, and A and B. 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.
