MOC3081SR2VM

Triac, SCR Output Optoisolators Overview

The MOC3081SR2VM is a single-channel zero-crossing triac driver optocoupler manufactured by onsemi. It features an infrared LED input coupled to a photo-triac output, providing electrical isolation with a rated insulation voltage of 5250 Vrms. The device supports surface-mount installation in a 6-SMD package and includes an integrated zero-crossing circuit that triggers the output only when the mains voltage is near zero, reducing electromagnetic interference. Key electrical parameters include a maximum forward current of 60 mA, a peak repetitive off-state voltage of 800 V, and a maximum gate trigger current of 15 mA. It operates within a temperature range of -40°C to +85°C.

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2VM' against the manufacturer's latest datasheet to confirm the reel packaging configuration and pin bending specifications. Ensure the selected component matches the required insulation voltage ratings for your application's safety standards. Cross-reference the part number with official distributor catalogs to confirm availability and lead times prior to ordering.

Triac, SCR Output Optoisolators Selection Notes

Select this component when zero-crossing switching is required to minimize electrical noise in AC control applications. Compare the 15 mA trigger current requirement against your driving circuit capabilities. Consider the 6-SMD footprint constraints during PCB layout. Verify that the 800 V blocking voltage meets the peak line voltage requirements of the target load.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3081M series of triac and SCR output optocouplers. It shares functional similarities with other devices in the family but differs in packaging and specific electrical tolerances. The SR2VM designation indicates a specific surface-mount variant optimized for automated assembly processes while maintaining the core zero-crossing functionality of the base model.

Triac, SCR Output Optoisolators Replacement Considerations

Direct substitutes may include other zero-crossing triac drivers from onsemi such as the MOC3081SVM or MOC3082M, provided they match the 6-pin SMD package and electrical ratings. Verify compatibility with existing PCB footprints and thermal management requirements before substitution.
