Product details

Triac output for AC load control

The MOC3012SM drives a Triac output rated for 250 V off-state, making it suitable for switching 120 VAC or 240 VAC loads like solenoids, lamps, and small motors through an external power Triac. With no zero-crossing circuit, the output fires immediately when the LED is triggered — this matters for phase-angle control or when the load must turn on at any point in the AC cycle, not just near the zero crossing.

Isolation and package for board integration

4170 Vrms isolation rating meets the reinforced insulation requirement for line-voltage safety barriers per IEC 60950-1, keeping the low-voltage control side electrically separate from the AC mains side.

Lifecycle and compliance snapshot

RoHS3 compliant and UL approved — the approvals cover the regulatory requirements for EU market access and North American safety certification, which most procurement teams need on the BOM line.

Frequently asked questions

What is the closest functional alternative to MOC3012SM?

The difference is in the LED trigger current spec; the MOC3012SM triggers at 5 mA max while the MOC3011SM triggers at a lower threshold. For most logic-driven circuits, the two are drop-in interchangeable on the same PCB footprint.

What compliance documentation does onsemi provide for MOC3012SM?

onsemi provides RoHS3 compliance (no exemptions) and UL recognition for the MOC3012SM. The UL file covers the reinforced isolation rating. No separate REACH or IEC certification is listed in the product record, but the RoHS3 declaration typically includes REACH compliance data in the manufacturer's documentation package.
