description
The TISP2290 is designed specifically for telephone equipment protection against lightning and transients induced by a.c. power lines. 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.
