description
These medium voltage dual symmetrical
transient voltage suppressor 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
SD3XAA
G
Terminals T, R and G correspond to the
alternative line designators of A, B and C
crowbar. The high crowbar holding current
prevents d.c. latchup as the current subsides.
These monolithic protection devices are
fabricated in ion-implanted planar structures to
