TISP61089ADR-S

The TISP61089ADR-S is a dual forward-conducting buffered P-gate Thyristor (SCR) Overvoltage Protector, designed to protect monolithic SLICs against overvoltage on the telephone line caused by lightning, AC power contact and induction. The programmable overvoltage protector limits voltage that exceed the SLIC supply rail voltage. Positive overvoltage is clipped to ground by diode forward conduction. Negative overvoltage is initially clipped close to the SLIC negative supply rail value. The protection voltage will then track the negative supply voltage and the overvoltage stress on the SLIC is minimized.
