Rated for 400 V off-state blocking voltage and a minimum static dV/dt of 1 kV/µs — the part resists false turn-on from fast line transients or inductive kickback that would otherwise trigger a standard Triac driver. The LED trigger current maximum is 15 mA with a typical forward voltage of 1.25 V, and the hold current is 400 µA typical — the downstream Triac stays latched once triggered until the load current drops below that threshold near the zero crossing. ## 6-SMD gull wing — rework and board integration Housed in a 6-SMD gull wing package with a 1.27 mm pitch — the leads are exposed and inspectable, so rework under a hot-air station is straightforward. The package body is small enough that preheating the board to 100–120 °C before removal prevents pad lifting. Supplied in tube, not tape-and-reel — factor this into the pick-and-place feeder setup if the line expects reel packaging.","metaTitle":"onsemi MOC3041SM Optoisolator, Triac Output, 4170Vrms","metaDescription":"onsemi MOC3041SM optoisolator with Triac output, 400V off-state, 4170Vrms isolation, zero-crossing circuit, UL approved, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tube","Output Type":"Triac","Turn On Time":"-","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Product Status":"Active","Approval Agency":"UL","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"1kV/µs","Base Product Number":"MOC304","Current - Hold (Ih)":"400µA (Typ)","Voltage - Isolation":"4170Vrms","Voltage - Off State":"400 V","Operating Temperature":"-40°C ~ 85°C","Zero Crossing Circuit":"Yes","Supplier Device Package":"6-SMD","Voltage - Forward (Vf) (Typ)":"1.25V","Current - DC Forward (If) (Max)":"60 mA","Current - LED Trigger (Ift) (Max)":"15mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0400","priceTiers":[{"qty":1,"price":"$1.12000","currency":"USD"},{"qty":10,"price":"$0.70700","currency":"USD"},{"qty":100,"price":"$0.52320","currency":"USD"},{"qty":500,"price":"$0.48078","currency":"USD"},{"qty":1000,"price":"$0.39593","currency":"USD"},{"qty":2000,"price":"$0.37614","currency":"USD"},{"qty":5000,"price":"$0.36765","currency":"USD"},{"qty":10000,"price":"$0.35917","currency":"USD"},{"qty":25000,"price":"$0.35484","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MOC3041SM/alternatives.json"},"ai":{"faq":[{"question":"What is the output type and what loads does it drive?","answer":"The output is a Triac with a zero-crossing circuit, rated for 400 V off-state.
