Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer designation carefully, as sources list both Isocom Components and onsemi for this part number. Confirm the specific suffix indicates the SMD/SMT gull-wing package variant rather than the standard DIP through-hole version. Ensure compliance with safety limit data per DIN EN/IEC 60747−5−5 for safe electrical insulation requirements in your final design.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triggering is required rather than zero-crossing detection. The 400 V peak rating suits lower voltage AC loads compared to higher voltage variants. Consider the 60 mA input current requirement for LED drive circuit sizing. Verify thermal management capabilities given the 330 mW power dissipation rating under continuous operation conditions.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC302_ series of optically coupled isolators. It combines a Gallium Arsenide infrared emitting diode with a light-triggered triac structure. The series is designed for general-purpose AC power switching where galvanic isolation between control and load circuits is essential.
