description
The TISP1082 is designed specifically for
telephone line card 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.
Negative 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. Positive
transients are clipped by diode action.
C(G)
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.
