Description

Relay Load Current

120

This Integrated Telecom Circuit combines a single-pole,

normally open (1-Form-A) solid state relay, a bridge

rectifier, a Darlington transistor, an optocoupler, and

three Zener diodes into one 16-pin SOIC package,

consolidating designs and reducing component count

in telecom applications.
