Description

The TISP61089BSD is a dual forward-conducting buffered p-gate thyristor (SCR) overvoltage protector. It is designed to protect monolithic

SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. The

TISP61089BSD limits voltages that exceed the SLIC supply rail voltage. The TISP61089BSD parameters are specified to allow equipment

compliance with Telcordia GR-1089-CORE, Issue 3 and ITU-T recommendations K.20, K.21 and K.45.
