Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against the official onsemi datasheet to confirm pinout and packaging details, as variations exist within the MOC3082 family. Ensure compliance with RoHS directives if required for the target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to reduce noise in AC load applications. Compare the 4170Vrms isolation rating against system requirements. Consider the 6-DIP package constraints for PCB layout. Evaluate the 800V blocking voltage suitability for the specific AC line voltage being controlled.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC308xM series of Triac output optoisolators from onsemi. It shares functional similarities with variants like MOC3082SM and MOC3082VM but differs in packaging and specific certification ratings. The series is widely used in industrial and consumer AC power control applications requiring galvanic isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes include MOC3082SM and MOC3082VM. Verify that replacement parts match the required isolation voltage and package type. Check for equivalent zero-crossing behavior and electrical characteristics before substitution.
