Thyristor TSPD 100V 5A 8-Pin SOIC T/R

It is a dual forward-conducting buffered p-gate over-voltage 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 device 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 -10 V to -70 V.These monolithic protection devices are fabricated in ion-implanted planar vertical power structures for high reliability and in normal system operation they are virtually transparent. The buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction.
