Thyristor TSPD 97V 8.6A 8-Pin SOIC T/R

This dual forward-conducting unidirectional overvoltage protector is designed for the overvoltage protection of ICs used for the SLIC (Subscriber Line Interface Circuit) function. The IC line driver section is typically powered with 0 V and a negative supply. The TISP1120F3D limits voltages that exceed these supply rails.High voltages can occur on the line as a result of exposure to lightning strikes and a.c. power surges. Negative transients are initially limited by breakdown clamping until the voltage rises to the breakover level, which causes the device to crowbar. The high crowbar holding current helps prevent d.c. latchup as the current subsides. Positive transients are limited by diode forward conduction. These protectors are designed to suppress and withstand the listed international lightning surges on any terminal pair
