MOC3032SM

Triac, SCR Output Optoisolators Overview

The MOC3032SM is a surface-mount optoisolator featuring a triac output and zero-crossing detection. It provides electrical isolation with a rated voltage of 5000Vrms. The device utilizes a 6-pin DIP package for PCB integration. Input is driven by an infrared LED, while the output switches AC loads via the internal triac. Zero-crossing technology minimizes electromagnetic interference during switching events. The component operates within a standard industrial temperature range.
