Triac, SCR Output Optoisolators Procurement Notes
Verify the specific suffix SR2M indicates surface mount packaging distinct from through-hole variants. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure ordering documentation matches the exact part number to avoid package confusion.
Triac, SCR Output Optoisolators Selection Notes
Select this component when surface mount assembly is required for zero-crossing triac driving. Compare against DIP versions if board space allows through-hole mounting. Verify that the 400V voltage rating meets the specific AC line requirements of the target application design.
Triac, SCR Output Optoisolators Part Context
This part belongs to the MOC304XM series of zero-cross optoisolators. It shares functional similarities with other members like MOC3041M and MOC3042M but differs in package type and specific voltage ratings. The series is designed for simplified logic control of 115 VAC power applications.
Triac, SCR Output Optoisolators Replacement Considerations
Direct substitutes include MOC3041SR2M and MOC3042SR2M from the same manufacturer family. Cross-reference datasheets to ensure identical pinout compatibility and matching voltage/current specifications before substitution.
