Littelfuse/IXYS ITC135P

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 Zener diodes into one 16-pin SOIC package, consolidating designs and reducing component count in telecom applications. The ITC135’s optocoupler provides for half-wave detection of ringing signals.
