It drives AC loads such as solenoids, relays, and small motors from a low-voltage control side while maintaining a reinforced isolation barrier for mains-referenced circuits. UL recognized and ROHS3 compliant, this part meets North American safety requirements and European substance restrictions without additional exemptions. ## Zero-crossing drive and dV/dt immunity The zero-crossing circuit triggers the Triac only when the AC line voltage is near zero, reducing inrush current and conducted EMI when switching resistive or lightly inductive loads. A minimum static dV/dt of 600 V/µs ensures the output remains off when exposed to fast voltage transients on the AC line — critical for avoiding false turn-on in noisy industrial environments. The typical holding current (Ih) is 500 µA, and the maximum LED trigger current (Ift) is 15 mA, allowing direct drive from a 5 V logic output with a series resistor. ## Package and assembly for automated lines The surface-mount footprint matches standard 6-pin SOP-6 layouts.","metaTitle":"onsemi MOC3081SR2M Optoisolator, Triac Output, 4170 Vrms","metaDescription":"onsemi MOC3081SR2M optoisolator with Triac output, 4170 Vrms isolation, 800 V off-state, zero-crossing circuit.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Triac","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Approval Agency":"UL","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"600V/µs","Current - Hold (Ih)":"500µA (Typ)","Voltage - Isolation":"4170Vrms","Voltage - Off State":"800 V","Operating Temperature":"-40°C ~ 85°C","Zero Crossing Circuit":"Yes","Supplier Device Package":"6-SMD","Voltage - Forward (Vf) (Typ)":"1.3V","Current - DC Forward (If) (Max)":"60 mA","Current - LED Trigger (Ift) (Max)":"15mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.35","stockQuantity":15,"priceTiers":[{"qty":1,"price":"$1.35000","currency":"USD"},{"qty":10,"price":"$0.85200","currency":"USD"},{"qty":100,"price":"$0.63060","currency":"USD"},{"qty":500,"price":"$0.57948","currency":"USD"},{"qty":1000,"price":"$0.47722","currency":"USD"},{"qty":2000,"price":"$0.45337","currency":"USD"},{"qty":5000,"price":"$0.44314","currency":"USD"},{"qty":10000,"price":"$0.43291","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ebf666b3e829cce190cd06090870c626.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What compliance documentation does onsemi provide for MOC3081SR2M?","answer":"onsemi provides ROHS3 compliance certification and UL recognition for the MOC3081SR2M.
