description
The TISP4xxxLP series is designed specifically
for telephone equipment protection against
lightning and transients induced by a.c. power
lines. These devices consist of a bidirectional
suppressor element connecting the A and B
terminals. They will suppress inter-wire voltage
transients.
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.
