The 4-LSOP (2.54mm pitch) gull-wing package is surface-mount ready, suiting it for reinforced isolation barriers in power supplies, motor drives, and industrial digital I/O modules. ## Current transfer ratio — gain margin for logic translation The CTR is specified at 130% minimum and 260% maximum when the LED forward current is 5mA. This range guarantees the output transistor saturates reliably when driving a 5V logic input through a pull-up resistor, even with LED current derated over the -55°C to 110°C operating range. The 400mV Vce saturation max at that drive level keeps the logic-low voltage well within TTL thresholds. ## Switching speed and drive timing Rise and fall times are 3.5µs and 5µs typical, with turn-on and turn-off times of 6µs and 5.5µs respectively. This places the part in the medium-speed class — adequate for 10-50 kHz PWM isolation or status feedback, but not for high-speed serial isolation above 100 kHz. The 1.16V typical forward voltage at 5mA LED current is standard for IR LEDs in this isolation class.","metaTitle":"VOL617A-8X001T Optocoupler, 5000Vrms, Transistor Output","metaDescription":"VOL617A-8X001T optocoupler: 5000Vrms isolation, transistor output, CTR 130-260% at 5mA, surface mount 4-LSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Signal Isolation"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","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":"5000Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 110°C","Rise / Fall Time (Typ)":"3.5µs, 5µs","Voltage - Output (Max)":"80V","Supplier Device Package":"4-LSOP (2.54mm)","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"260% @ 5mA","Current Transfer Ratio (Min)":"130% @ 5mA","Voltage - Forward (Vf) (Typ)":"1.16V","Turn On / Turn Off Time (Typ)":"6µs, 5.5µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6","priceTiers":[{"qty":1,"price":"$0.50000","currency":"USD"},{"qty":10,"price":"$0.31100","currency":"USD"},{"qty":100,"price":"$0.17860","currency":"USD"},{"qty":1000,"price":"$0.13977","currency":"USD"},{"qty":3000,"price":"$0.12812","currency":"USD"},{"qty":6000,"price":"$0.11647","currency":"USD"},{"qty":15000,"price":"$0.10871","currency":"USD"},{"qty":30000,"price":"$0.10483","currency":"USD"},{"qty":75000,"price":"$0.10094","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/87de4ca24d2fe38fa765af21a2d62eb6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/VOL617A-8X001T/alternatives.json"},"ai":{"faq":[{"question":"What is the current transfer ratio of VOL617A-8X001T?","answer":"The CTR is 130% minimum and 260% maximum at 5mA LED forward current."},{"question":"Is VOL617A-8X001T suitable for 5V logic?","answer":"Yes.
