TISP61089ADR-S

It is a dual forward-conducting buffered p-gate thyristor (SCR) overvoltage protectors. They are 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 ‘61089 limits voltages that exceed the SLIC supply rail voltage.It is intended to be used with a series resistance of at least 25 ? and a suitable overcurrent function for Telcordia compliance.The buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction. The regular pin-out for surface mount and through-hole packages is a feed through configuration.
