description
The TISP2290L 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.
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.
