It provides 3750 Vrms galvanic isolation between input and output, with a transistor output rated to 80 V and 50 mA continuous. ## CTR range and aging margin Current transfer ratio is specified at 40% minimum and 80% maximum, both measured at a forward current of 10 mA. The 40% floor leaves room for LED aging over the product lifetime — a common failure mode in isolated feedback loops where CTR drift can push a regulator out of regulation. Designing with the minimum CTR rather than the typical value ensures the circuit still switches correctly years into service. ## Temperature range and switching speed Rise and fall times are 3 µs and 4 µs typical, with turn-on and turn-off times both 5 µs. ## Package and footprint Housed in a 4-pin SOIC package (4.40 mm width, 0.173\" body) with a 4-SSOP supplier device package designation. Surface-mount assembly compatible with standard reflow profiles.","metaTitle":"VOS615A-1X001T Optocoupler, Phototransistor Output","metaDescription":"VOS615A-1X001T single-channel phototransistor optocoupler, 40–80% CTR at 10 mA, 3750 Vrms isolation, -55 to 110°C.","metaKeywords":null},"attributes":{"series":"VOS615A","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":[],"specifications":{"Series":"VOS615A","Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"4-SOIC (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"3750Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"3µs, 4µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-SSOP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"80% @ 10mA","Current Transfer Ratio (Min)":"40% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.2V","Turn On / Turn Off Time (Typ)":"5µs, 5µs","Current - DC Forward (If) (Max)":"50 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.56","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.56000","currency":"USD"},{"qty":10,"price":"$0.36800","currency":"USD"},{"qty":100,"price":"$0.24360","currency":"USD"},{"qty":1000,"price":"$0.18808","currency":"USD"},{"qty":3000,"price":"$0.16995","currency":"USD"},{"qty":6000,"price":"$0.15862","currency":"USD"},{"qty":15000,"price":"$0.15295","currency":"USD"},{"qty":30000,"price":"$0.15069","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/06cd86c391d2fa372d99abdc33e41f69.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) of VOS615A-1X001T?","answer":"The CTR is specified as 40% minimum and 80% maximum at a forward current of 10 mA.
