Description
The TISP61511D is a dual forward-conducting buffered p-gate overvoltage protector. It is designed to protect monolithic Subscriber Line Interface Circuits, SLICs, against overvoltages on the telephone line caused by lightning, ac power contact and induction. The TISP61511D limits voltages that exceed the SLIC supply rail voltage.

Dual Voltage-Programmable Protectors.
    – Wide 0 to -80 V Programming Range
    – Low 5 mA max. Triggering Current
    – High 150 mA min. Holding Current
