Description

These dual forward-conducting unidirectional over-voltage

protectors are 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 TISP1xxxF3 limits voltages

that exceed these supply rails and is offered in two voltage

variants to match typical negative supply voltage values.

High voltages can occur on the line as a result of exposure

to lightning strikes and a.c. power surges. Negative tran-

sients 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 pre-

vents d.c. latchup as the current subsides. Positive tran-

sients are limited by diode forward conduction. These pro-

tectors are guaranteed to suppress and withstand the listed

international lightning surges on any terminal pair.
