Its 5300 Vrms isolation rating makes it suitable for breaking ground loops and providing safety isolation in power supplies, motor drives, and industrial controls. ## CTR range and switching speed for BOM margin Current transfer ratio spans 100% to 200% at a forward current of 5 mA, giving a 2:1 gain window that accommodates LED degradation and temperature drift without redesigning the load resistor. Typical rise and fall times are 2 µs each, with turn-on at 3 µs and turn-off at 2.3 µs — fast enough for 100 kHz switching or serial data isolation below 1 Mbps. ## Active production — no obsolescence concern It is ROHS3 compliant. Sourced per RFQ against your BOM quantity — confirm the package and CTR bin before committing. ## 4-SMD Gull Wing — rework-friendly footprint Housed in a 4-SMD Gull Wing package, the leads are visible and accessible for inspection and hand rework. The 400 mV max Vce saturation at 50 mA output current means the transistor drops less than half a volt when fully on, keeping dissipation low in the 4-SMD body.","metaTitle":"VO617A-3X018T Vishay Optocoupler – 5300 Vrms, 100-200% CTR","metaDescription":"Vishay VO617A-3X018T single-channel transistor-output optocoupler. 5300 Vrms isolation, 100-200% CTR at 5 mA, 4-SMD Gull Wing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Bulk","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"4-SMD, Gull Wing","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5300Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"2µs, 2µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-SMD","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"200% @ 5mA","Current Transfer Ratio (Min)":"100% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.35V","Turn On / Turn Off Time (Typ)":"3µs, 2.3µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.43","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.43000","currency":"USD"},{"qty":10,"price":"$0.26300","currency":"USD"},{"qty":100,"price":"$0.15100","currency":"USD"},{"qty":1000,"price":"$0.11817","currency":"USD"},{"qty":2000,"price":"$0.10832","currency":"USD"},{"qty":5000,"price":"$0.09848","currency":"USD"},{"qty":10000,"price":"$0.09191","currency":"USD"},{"qty":25000,"price":"$0.08863","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/696667aedd428c875747efe4d7845ee2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio of VO617A-3X018T?","answer":"The VO617A-3X018T has a CTR range of 100% to 200% at a forward current of 5 mA.
