DESCRIPTION
This device has been especially designed to protect a subscriber line card interface (SLIC) against transient overvoltage.
Positive overloads are clipped with two diodes, while negative surges are suppressed by two protection thyristors, their breakdown voltage being is referencedto the -Vbat.
This component presents a very low gate triggering current (IGT) in order to reduce the current consumption on the PC board during the firing phase.

FEATURES
■ DUAL PROGRAMMABLE TRANSIENT SUPPRESSOR
