MOC3052FM

Triac, SCR Output Optoisolators Overview

The onsemi MOC3052FM is a single-channel optoisolator featuring a Triac output, designed for high-voltage isolation applications. It operates without a zero-crossing circuit, allowing random phase triggering of triacs and SCRs. The device provides a peak isolation voltage of 7500Vpk and supports a maximum off-state repetitive peak voltage (VDRM) of 600V. It is housed in a 6-SMD surface-mount package.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triggering capability for precise control of AC power loads
• High-voltage isolation with a peak rating of 7500Vpk
• Surface-mount packaging for automated assembly integration

Triac, SCR Output Optoisolators Applications

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix to confirm the exact isolation voltage rating and package variant. Confirm RoHS compliance status through official documentation. Ensure the component meets the required operating temperature range for the target environment. Cross-reference datasheet electrical characteristics against system design limits.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase control is required rather than zero-crossing switching. Consider the 6-SMD footprint for space-constrained PCB layouts. Evaluate the 600V VDRM rating against the peak line voltage of the application. Verify that the input current requirements align with the driving logic levels.
