FEATURES

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 referenced to the -Vbat.

This component presents a very low gate

current consumption on the PC board during the

firing phase.
