MOC3022VM

Triac, SCR Output Optoisolators Overview

The onsemi MOC3022VM is a single-channel Triac and SCR output optocoupler designed for random phase triac driver applications. It features a DIP-6 through-hole package with an isolation voltage of 5300 Vrms. The device operates within a temperature range of -40°C to +85°C and includes a maximum forward current of 60 mA. Key electrical parameters include a peak repetitive off-state voltage (VDRM) of 400 V, a maximum trigger current of 10 mA, and a power dissipation rating of 330 mW.

Triac, SCR Output Optoisolators Feature Summary

• Random phase triggering capability suitable for AC power control circuits without zero-crossing detection
• High isolation voltage ensuring safe separation between control and load sides
• Robust thermal performance supporting operation in demanding industrial environments

Triac, SCR Output Optoisolators Applications

• Solid state relays for AC load switching
• Industrial motor control systems
• Heating element regulation circuits

Triac, SCR Output Optoisolators Procurement Notes

Verify the specific suffix 'VM' corresponds to the PDIP-6 tube packaging configuration as documented. Confirm that the 5300 Vrms isolation rating aligns with your safety certification requirements. Ensure the 400 V VDRM specification meets the peak voltage demands of the target AC line application before finalizing component selection.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random phase firing is required rather than zero-crossing switching. The 400 V blocking voltage limits suitability for higher voltage mains applications. Consider the 60 mA forward current limit for LED drive circuit design. The DIP-6 package facilitates manual assembly or standard through-hole reflow processes compared to surface mount alternatives.

Triac, SCR Output Optoisolators Part Context

This device belongs to the MOC302x series of random phase TRIAC drivers from onsemi. It shares functional similarities with the MOC3021 and MOC3023 but differs in specific trigger current characteristics and voltage ratings. The MOC3022VM provides a balanced solution for general-purpose AC power control where precise timing relative to the AC waveform zero crossing is not critical.
