The base pin gives the designer the option to add a base-emitter resistor for improved noise immunity or to tailor the switching speed — a feature not available on standard three-pin phototransistor optos. The 6-SMD Gull Wing footprint is common across this isolation class, so the board layout transfers cleanly if a second-source candidate is needed later. ## CTR window: 100% to 200% at 10 mA forward current The guaranteed current transfer ratio of 100% minimum to 200% maximum at IF = 10 mA means the output transistor is guaranteed to saturate with as little as 10 mA LED drive, and the upper bound prevents the output from saturating too hard and slowing turn-off. This window is tighter than the typical 50-600% range on commodity phototransistor optos, which makes the SFH601-3X017T a better fit for designs where the LED current budget is constrained or where the load resistor value needs a predictable collector current swing. ## Switching speed and output ratings Rise and fall times are 2 µs typical each, with turn-on time of 3 µs and turn-off of 2.3 µs. That places this part in the medium-speed class — fine for 50/60 Hz mains zero-cross detection, relay coil drive, or isolated digital inputs up to a few tens of kHz, but not for high-speed data isolation. The output transistor is rated for 100 V collector-emitter and 50 mA continuous current, with a maximum VCE(sat) of 400 mV at the rated drive. The 1.25 V typical forward voltage on the LED side is standard for an infrared GaAs emitter. ## Temperature range and environment It does not carry an AEC-Q automotive qualification, so it is not a first choice for under-hood or chassis-domain applications, but the wide temperature margin suits most factory-floor and base-station environments where the board sees ambient heat from nearby power stages.","metaTitle":"SFH601-3X017T Optocoupler, 5000Vrms, 6-SMD Gull Wing","metaDescription":"SFH601-3X017T Vishay optocoupler with transistor base output, 5000Vrms isolation, 100-200% CTR at 10mA, -55°C to 100°C, surface mount 6-SMD package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor with Base","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","lifecycle_stage":"eol_hot","Number of Channels":"1","Voltage - Isolation":"5000Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"2µs, 2µs","Voltage - Output (Max)":"100V","Supplier Device Package":"6-SMD","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"200% @ 10mA","Current Transfer Ratio (Min)":"100% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.25V","Turn On / Turn Off Time (Typ)":"3µs, 2.3µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.59","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.59000","currency":"USD"},{"qty":10,"price":"$1.00500","currency":"USD"},{"qty":100,"price":"$0.74370","currency":"USD"},{"qty":500,"price":"$0.68336","currency":"USD"},{"qty":1000,"price":"$0.56277","currency":"USD"},{"qty":2000,"price":"$0.53464","currency":"USD"},{"qty":5000,"price":"$0.52257","currency":"USD"},{"qty":10000,"price":"$0.51052","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/48b671b6e7c71d4ee65ddb8e75394c15.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the current transfer ratio (CTR) of SFH601-3X017T?","answer":"The CTR is guaranteed between 100% and 200% at a forward current of 10 mA."},{"question":"Is SFH601-3X017T RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay/SFH601-3X017T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay/SFH601-3X017T when reusing this data.
