It is designed to drive a power triac or SCR from a low-voltage DC logic signal while providing galvanic isolation between the control side and the AC mains side. The zero-crossing circuit ensures the output triac only turns on near the AC line voltage zero crossing, which minimizes inrush current and conducted EMI when switching resistive or lightly inductive loads. The off-state voltage rating of 400 V suits 120 VAC and 240 VAC line applications; the minimum static dV/dt of 1 kV/µs provides immunity against false triggering from line transients or commutating noise. ## Key ratings that drive BOM decisions The typical forward voltage (Vf) is 1.25 V, and the LED can be driven up to 60 mA continuous. The hold current (Ih) is 400 µA typical — once triggered, the triac latches until the load current drops below this threshold near the AC zero crossing. This is standard for triac-output optoisolators and matches common power triac gate drive requirements. ## Sourcing and compliance status The part carries UL and IEC/EN/DIN approvals.","metaTitle":"MOC3041SR2VM onsemi Optoisolator Triac Output, 4170 Vrms","metaDescription":"MOC3041SR2VM onsemi optoisolator with triac output, 4170 Vrms isolation, zero-crossing circuit, 400 V off-state, 6-SMD gull wing.
