MOC3022SM

Triac, SCR Output Optoisolators Overview

The MOC3022SM is a random phase triac output optoisolator manufactured by Isocom Components 2004 LTD. It features a gallium arsenide infrared LED coupled to a triac detector within a compact 6-SMD, Gull Wing package. The device provides electrical isolation with a rated isolation voltage of 5000Vrms and supports an off-state voltage up to 400V. Designed for non-zero crossing switching applications, it ensures reliable triggering of triacs or SCRs in AC power control circuits without specific timing constraints.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triac output configuration for flexible AC load control
• High isolation voltage rating ensuring safe circuit separation
• Compact surface mount packaging suitable for automated assembly

Triac, SCR Output Optoisolators Applications

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

Triac, SCR Output Optoisolators Procurement Notes

Verify the exact suffix against the manufacturer's current ordering guide to confirm pinout compatibility and lead-free status. Ensure the selected variant matches the required isolation voltage and package dimensions for your PCB layout. Cross-reference the datasheet revision date to confirm compliance with current safety standards before finalizing component selection.

Triac, SCR Output Optoisolators Selection Notes

Select this component when non-zero crossing switching is acceptable for the application. Verify that the peak repetitive off-state voltage requirement does not exceed 400V. Confirm that the 6-SMD gull wing footprint aligns with the target PCB design. Ensure the input forward current requirements are compatible with the driving logic levels available in the system.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC302x series of triac output optocouplers from Isocom Components 2004 LTD. The series includes variants such as MOC3020, MOC3021, MOC3022, and MOC3023, which differ primarily in their zero-crossing detection capabilities. The MOC3022 specifically lacks zero-crossing detection, allowing for immediate turn-on upon signal receipt.

Triac, SCR Output Optoisolators Replacement Considerations

Compatible substitutes include MOC3021M and MOC3023M from the same manufacturer family. Verify that alternative parts match the 6-SMD gull wing package and maintain equivalent isolation voltage ratings. Check if the replacement offers zero-crossing functionality if noise reduction is required.
