TISP61521DR-S

The TISP61521 is a dual forward-conducting buffered p-gate 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 TISP61521 limits voltages that exceed the SLIC supply rail voltage.The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of -20 V to -150 V.The TISP61521 buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction. The TISP61521 is available in an 8-pin plastic small-outline surface mount package.
