Product Summary

The ITC137P is an Integrated Telecom Circuit. It combines a 1-Form-A solid state relay, bridge rectifier, Darlington transistor, optocoupler and zener diodes into one 16 pin SOIC package, consolidating designs and reducing component count in telecom applications. The ITC137P’s optocoupler provides for ful wave detection of the ring signal.
