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.

Terminals T, R and G correspond to the
alternative line designators of A, B and C
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.
