Its 5300 Vrms isolation rating covers reinforced insulation requirements in medical, industrial, and power-supply applications where a standard 3750 Vrms part would need a second device or external creepage. The 40% to 80% current transfer ratio at 5 mA forward current gives enough gain to drive logic inputs or microcontroller GPIOs directly without a post-amplifier, and the 80 V collector-emitter breakdown handles 24 V and 48 V bus rails cleanly. ## What the CTR range means for your drive budget The 40% minimum CTR at 5 mA is the number to design against when calculating the pull-up resistor and the input threshold margin over temperature. A 5 mA LED drive yields at least 2 mA collector current, which saturates a 4.7 kΩ pull-up to 5 V logic cleanly. The 80% maximum CTR prevents the output from saturating too deeply, keeping turn-off time predictable at 2.3 µs typical. If the LED current drops below 5 mA due to a weak drive or series resistance, the CTR falls off — stay above 3 mA to stay inside the guaranteed range. ## Lifecycle and production status ROHS3 compliant per the supplier declaration. For BOM risk assessment, this part is still a safe selection for new designs and volume production. ## Temperature range and deployment environment Rated for -55°C to 110°C operating ambient, the VO617A-1 suits outdoor telecom cabinets, industrial motor drives, and power converters that see wide thermal cycling. The 110°C upper limit exceeds the typical 85°C industrial grade, giving margin in confined enclosures or near heat sinks. The through-hole 4-DIP package with 7.62 mm pin pitch keeps creepage distance consistent with the 5300 Vrms rating — no conformal-coat derating needed for basic insulation.","metaTitle":"VO617A-1 Optocoupler, 5.3kV Isolation, 40-80% CTR, 4-DIP","metaDescription":"VO617A-1 single-channel transistor output optocoupler with 5300Vrms isolation, 40-80% CTR at 5mA, -55°C to 110°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tube","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Through Hole","Package / Case":"4-DIP (0.300\\\", 7.62mm)","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-DIP","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"80% @ 5mA","Current Transfer Ratio (Min)":"40% @ 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":"$0.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.61000","currency":"USD"},{"qty":10,"price":"$0.40200","currency":"USD"},{"qty":100,"price":"$0.26570","currency":"USD"},{"qty":1000,"price":"$0.20518","currency":"USD"},{"qty":2000,"price":"$0.18540","currency":"USD"},{"qty":5000,"price":"$0.17304","currency":"USD"},{"qty":10000,"price":"$0.16686","currency":"USD"},{"qty":25000,"price":"$0.16439","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/696667aedd428c875747efe4d7845ee2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio of VO617A-1?","answer":"The VO617A-1 has a current transfer ratio of 40% minimum to 80% maximum, measured at 5 mA forward current.
