Triac, SCR Output Optoisolators Procurement Notes

Verify current availability status as this specific part number may be classified as obsolete or discontinued by the manufacturer. Confirm compatibility with existing PCB footprints and reflow soldering profiles if sourcing from third-party distributors. Ensure that any substitute components meet the same electrical isolation and voltage rating specifications required for the application safety standards.

Triac, SCR Output Optoisolators Selection Notes

Select this component when high-voltage isolation and zero-crossing functionality are required for AC load control. Consider the 800 V off-state voltage rating to ensure it exceeds the peak line voltage of the target application. Evaluate the surface-mount package constraints against assembly capabilities. Verify that the trigger current requirements align with the driving logic levels available in the system design.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC3082M series of Triac output optocouplers. It shares functional similarities with other members of the family but differs in packaging and specific manufacturing revisions. The FR2M suffix typically denotes a tape-and-reel surface-mount variant, distinguishing it from through-hole DIP versions like the MOC3082VM or standard tube-packaged SMD variants.

Triac, SCR Output Optoisolators Replacement Considerations

Public sources indicate this part is obsolete. Potential substitutes include other onsemi zero-crossing Triac optocouplers such as the MOC3081M or MOC3083M, provided they match the 800 V rating and pinout compatibility. Verify datasheet parameters for equivalent isolation voltage and trigger characteristics before implementation.
