Description
These '61089 parts are 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. The '61089 parameters are specified to allow equipment compliance with Telcordia (formally Bellcore) GR-1089-CORE and ITU-T recommendations K.20, K.21, and K.45.
