description

These high voltage dual symmetrical transient

voltage suppressor devices are designed to

protect

telecommunication

applications

with

battery backed ringing against transients caused

by lightning strikes and a.c. power lines. Offered

in five voltage variants to meet battery and

protection requirements they are guaranteed to

suppress and withstand the listed international

lightning surges in both polarities. Transients are

initially clipped by breakdown clamping until the

voltage rises to the breakover level, which
