Its 5000 Vrms isolation rating and 600 V off-state voltage suit it for mains-referenced applications where safety isolation is mandatory. The zero-crossing circuit ensures the output triac turns on only near the AC line zero-crossing, minimising inrush current and conducted EMI — a benefit for resistive heater, lamp, and motor contactor loads. ## Transient immunity and trigger thresholds A minimum static dV/dt of 10 kV/µs prevents false turn-on from fast voltage spikes on the output side, critical in industrial environments with inductive load switching or nearby contactors. The LED trigger current (Ift) is 1.3 mA max, allowing direct drive from a 3.3 V or 5 V logic output with a series resistor. Forward voltage is 1.25 V typical, and maximum continuous LED current is 30 mA. Turn-on time is 60 µs, fast enough for most AC switching cycles but not intended for high-frequency PWM. The hold current (Ih) is 500 µA, meaning the output triac will commutate off when the load current drops below this level near the AC zero-cross. ## Active lifecycle and compliance status This supports ongoing BOM stability for production runs requiring a UL- and CSA-approved optotriac. The part is in a 6-SMD gull-wing package, surface-mount for automated assembly. Operating temperature range is -55°C to 100°C, covering industrial and outdoor enclosures.","metaTitle":"FOD4116SD onsemi Optoisolator – 5 kV Triac, Zero-Cross","metaDescription":"onsemi FOD4116SD optoisolator: 5000 Vrms isolation, triac output, zero-crossing circuit, 10 kV/µs dV/dt immunity, 600 V off-state.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Bulk","Output Type":"Triac","Turn On Time":"60µs","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Approval Agency":"CSA, UL","lifecycle_stage":"eol_hot","Number of Channels":"1","Static dV/dt (Min)":"10kV/µs","Current - Hold (Ih)":"500µA","Voltage - Isolation":"5000Vrms","Voltage - Off State":"600 V","Operating Temperature":"-55°C ~ 100°C","Zero Crossing Circuit":"Yes","Supplier Device Package":"6-SMD","Voltage - Forward (Vf) (Typ)":"1.25V","Current - DC Forward (If) (Max)":"30 mA","Current - LED Trigger (Ift) (Max)":"1.3mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.13","stockQuantity":0,"priceTiers":[{"qty":126,"price":"$2.39000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/49cf8eca9dd44957a150c4b466b221d4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is FOD4116SD zero-crossing?","answer":"Yes, the FOD4116SD includes a zero-crossing circuit, which gates the triac output on only near the AC line zero-crossing to reduce inrush and EMI."},{"question":"What is the closest pin-compatible alternative to FOD4116SD?","answer":"The FOD4116SD is part of onsemi's FOD4116 family.
