H11C4SD

Triac, SCR Output Optoisolators Overview

The onsemi H11C4SD is a single-channel optoisolator featuring an SCR output, designed for surface-mount applications in a 6-SMD package. It provides electrical isolation with a rated voltage of 5300Vrms and supports a blocking voltage of 400V. The device operates without zero-crossing detection capabilities, making it suitable for phase-control applications where precise timing synchronization is not required. It accepts DC input signals to trigger the silicon-controlled rectifier output.
