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.
