Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'R2' indicates reel packaging when sourcing. Confirm that the component meets RoHS requirements if restricted substances are a constraint. Ensure the selected variant matches the required surface-mount footprint and pin configuration for PCB layout compatibility. Cross-reference the datasheet for any recent product change notifications regarding lead frame materials or marking changes.

Triac, SCR Output Optoisolators Selection Notes

Select this component for applications requiring high isolation voltage and surface-mount convenience. The non-zero-crossing feature makes it appropriate for dimming and phase-control circuits where precise timing is necessary. Consider the 800 V blocking voltage for standard AC line applications. Verify thermal management needs as the device dissipates power during operation. Compare against zero-crossing variants if noise reduction is prioritized over phase control precision.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3072M series of Triac and SCR output optocouplers from onsemi. It is designed for general-purpose AC switching and isolation tasks. The series offers various packaging options, including through-hole and surface-mount versions, to accommodate different manufacturing processes. It serves as a reliable interface between low-voltage control logic and high-voltage AC loads.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other MOC3072 series variants with different packaging, such as MOC3072SVM for DIP-style surface mount or MOC3072M for through-hole. Ensure replacement parts maintain the same 4170 Vrms isolation rating and 800 V VDRM specification. Verify that the alternative also supports non-zero-crossing operation if phase control is required.
