devices

are

designed to protect ISDN and telecommunication

applications with ground backed ringing against

transients caused by lightning strikes and a.c.

power lines. Offered in three 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 causes the device to
