Rated for 400 V off-state voltage and a minimum static dV/dt of 1 kV/µs, this part is built to switch resistive or inductive AC loads without false triggering on line transients. ## Zero-crossing circuit — why it matters for the BOM The zero-crossing circuit turns on the Triac only when the AC mains voltage crosses near zero, which reduces inrush current into the load and lowers conducted EMI at switch-on. This makes the MOC3041SVM a natural fit for driving resistive loads like heaters or incandescent lamps where soft turn-on extends relay and triac life. The LED trigger current (Ift) is 15 mA max, and the typical hold current (Ih) is 400 µA — the input side needs a 15 mA forward current to latch the output, and the triac stays on until the load current drops below 400 µA. ## Package and board-fit — 6-SMD Gull Wing Housed in a 6-SMD Gull Wing package, the MOC3041SVM is a surface-mount part supplied in Tube — the Gull Wing leads provide a visible solder joint for inspection and rework. Approvals include IEC/EN/DIN and UL — the UL listing covers the 4170Vrms isolation rating, which is the figure a safety engineer uses to demonstrate reinforced insulation in a power supply or motor drive interface.","metaTitle":"onsemi MOC3041SVM Optoisolator Triac, 4170Vrms, Zero-Cross","metaDescription":"onsemi MOC3041SVM optoisolator with Triac output, 4170Vrms isolation, zero-crossing circuit, 400V off-state, surface mount 6-SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"IEC/EN/DIN, 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":"$1.7600","priceTiers":[{"qty":486,"price":"$0.62000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MOC3041SVM/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between MOC3041SVM and MOC3073SVM?","answer":"The MOC3073SVM lacks a zero-crossing circuit — it switches the triac on at any point in the AC cycle, which can cause higher inrush current and EMI.
