MOC3022SR2M

Triac, SCR Output Optoisolators Overview

The MOC3022SR2M is a Triac driver output optocoupler from onsemi, designed for AC input applications. It features a single channel with a 6-pin SMD package (6-SMD,鸥翼). Key electrical parameters include an isolation voltage of 4170Vrms and a maximum forward current of 60mA. The device operates within a temperature range of -40°C to 85°C. It has a peak repetitive off-state voltage of 400V and a typical holding current of 100µA. The component is non-zero crossing type and is certified by UL.

Triac, SCR Output Optoisolators Feature Summary

• Provides galvanic isolation between control circuitry and high-voltage AC loads using a Triac output stage.
• Designed for surface mount installation in compact electronic assemblies.
• Capable of driving Triacs directly without requiring external zero-crossing detection circuits.

Triac, SCR Output Optoisolators Applications

• Solid state relay modules
• AC motor speed control systems
• Lighting dimmer circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'SR2M' to ensure the correct surface mount package variant is ordered, as lead times may vary by distributor. Confirm that the 4170Vrms isolation rating meets the safety requirements of the target application. Check for RoHS compliance status if environmental regulations apply. Ensure the 6-SMD footprint matches the PCB design constraints. Validate the non-zero crossing characteristic against system noise immunity needs.

Triac, SCR Output Optoisolators Selection Notes

Select this component when a surface mount solution is required for isolating low-power control signals from AC power stages. The 400V blocking voltage suits lower voltage AC applications. Consider the non-zero switching behavior for general purpose load control where precise phase alignment is not critical. Compare thermal dissipation capabilities against the expected duty cycle. Ensure the 60mA forward current limit is sufficient for the LED drive source.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302 series of Triac driver optocouplers. It shares functional similarities with through-hole variants like the MOC3022 but utilizes a surface mount package for automated assembly. The series is commonly used in industrial controls and consumer appliances requiring reliable AC switching with electrical isolation.

Triac, SCR Output Optoisolators Replacement Considerations

Direct pin-compatible replacements may include other MOC302x series devices in SMD packages, such as MOC3021SR2M or MOC3023SR2M, provided their voltage and current ratings are compatible. Verify package dimensions and isolation voltage before substitution.
