Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount package variant. Confirm the manufacturer designation as Isocom Components 2004 LTD. Ensure the non-zero crossing characteristic matches the design requirements. Check for RoHS compliance status if required by the assembly process.

Triac, SCR Output Optoisolators Selection Notes

Select this component when immediate turn-on is preferred over zero-crossing to reduce inrush current stress on resistive loads. The surface mount package suits automated PCB assembly. Verify that the 400V blocking voltage meets the peak line voltage requirements of the target application.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302x series of triac output optocouplers. It shares functional similarities with the through-hole MOC3022 but utilizes a surface mount footprint. The series is designed for general-purpose AC switching and isolation tasks in consumer and industrial electronics.

Triac, SCR Output Optoisolators Replacement Considerations

The MOC3021XSM is a comparable alternative within the same family, offering similar isolation and pinout characteristics. Verify compatibility regarding the specific switching behavior and voltage ratings before substitution.
