MOC3041M
onsemiMOC3041M is an onsemi 6-pin DIP zero-cross triac driver output optocoupler — 400 V peak off-state voltage, 15 mA maximum LED trigger current, 4170 VACRMS isolation, tube packing of 50 (M suffix; SR2M is the tape-and-reel version), -40 to +85 °C. The zero-cross detector is the selection point: it fires the external triac only at line-voltage zero crossing, suppressing inrush current and EMI for resistive AC loads at 115/240 VAC. Selection advice: this is a trigger device, not a load driver — it must not drive a load directly; always use it with an external triac or back-to-back SCR pair per the datasheet circuits. For random-phase firing choose the MOC3021 series instead. The MOC303x family is the lower 250 V peak counterpart — confirm 400 V peak for 240 VAC mains. onsemi lists this code as Active. Evidence: onsemi MOC303XM/MOC304XM datasheet confirms zero-cross triac driver, 400 V peak, 15 mA IFT, 4170 VACRMS isolation and 6-pin DIP tube packing. Match the full MOC3041M code for phase type and packing.

MOC3041M FAQ
What should I check before substituting MOC3041M with another Triac driver output optocoupler?
Match the full ordering code, not the series name: package (DIP-6), temperature grade and packing all ride on the suffixes. A same-series code in a different package is a different orderable device, so confirm the substitute against the onsemi datasheet before changing the BOM.
