MOC3012VM

Triac, SCR Output Optoisolators Overview

The MOC3012VM is a random-phase Triac driver output optocoupler manufactured by onsemi (formerly Fairchild). It features a PhotoTriac output with no zero-crossing circuit, suitable for AC power control. Key electrical parameters include a peak blocking voltage of 250 V, an isolation voltage of 5300 Vrms, and a maximum forward current of 60 mA. The device operates within a temperature range of -40°C to +85°C and is housed in a PDIP-6 package.

Triac, SCR Output Optoisolators Feature Summary

• Random-phase triggering capability allows Triac firing at any point in the AC cycle.
• High isolation voltage ensures safe separation between control and load circuits.
• IR emitting diode provides excellent stability with low degradation over time.

Triac, SCR Output Optoisolators Applications

• Solid-state relays
• Motor speed controls
• Lighting dimmers

Triac, SCR Output Optoisolators Procurement Notes

Verify the manufacturer status as onsemi acquired Fairchild Semiconductor. Confirm the specific suffix 'FVM' or 'VM' matches the required packaging and compliance specifications. Check availability as some variants may be discontinued or subject to long lead times. Ensure the PDIP-6 through-hole package fits the design constraints.

Triac, SCR Output Optoisolators Selection Notes

Select this component when random-phase triac triggering is required rather than zero-crossing switching. Verify that the 250V peak blocking voltage meets the load requirements. Consider the 5300 Vrms isolation rating for safety compliance. Ensure the operating temperature range covers the application environment.

Triac, SCR Output Optoisolators Part Context

This part belongs to the MOC3012M series of Triac driver output optocouplers. It is designed for general-purpose AC power control applications where phase-angle control is necessary. The device integrates an infrared emitting diode and a light-sensitive Triac in a single package.

Triac, SCR Output Optoisolators Replacement Considerations

Check for direct pin-compatible substitutes from onsemi or other manufacturers offering similar random-phase Triac drivers with comparable voltage ratings and isolation levels.
