The zero-crossing circuit fires the internal Triac only when the AC voltage crosses the zero point, so the load sees a clean sine-wave start and the board avoids the conducted EMI that a mid-cycle switch-on radiates back onto the mains. Rated 400 V off-state blocking voltage, the output stage can handle 240 VAC and 277 VAC line switching with headroom for transient spikes that ride the sine wave. ## 4170 Vrms isolation barrier — reinforced-grade certification Isolation is rated at 4170 Vrms, which meets reinforced-grade requirements per IEC/EN/DIN and UL standards — the barrier is certified for direct connection between a microcontroller-side low-voltage circuit and a mains-voltage load without additional galvanic protection on the board. Minimum static dV/dt is 1 kV/µs — this is the immunity spec that matters when the Triac is driving an inductive load (a relay coil or motor starter) whose back-EMF could otherwise trigger the output falsely and latch the load on past the intended turn-off point. The 400 µA typical hold current means the output Triac stays latched once triggered until the load current drops below that threshold at the next AC zero crossing — consistent with the zero-crossing turn-off behaviour a designer expects from this class of optoisolator. ## Through-hole 6-DIP — board-fit and sourcing reality Housed in a 6-DIP (0.300-inch, 7.62 mm pitch) through-hole package, the MOC3041VM mates with standard 0.100-inch DIP sockets or solders directly into the PCB — no fine-pitch reflow, no moisture-sensitivity level to track on the assembly line. ROHS3 compliant with no exempted lead in the solder finish; UL and IEC/EN/DIN certification on the isolation barrier means the part passes a safety audit without a separate agency review at the board level.","metaTitle":"onsemi MOC3041VM Optoisolator, Triac Output, 4170 Vrms","metaDescription":"onsemi MOC3041VM optoisolator with triac output, 4170 Vrms isolation, zero-crossing circuit, 400 V off-state, 1 kV/µs dV/dt.
