The 400mV Vce(sat) ceiling at 50mA output ensures the output stays in saturation across the load range. ## Temperature range and package — board-fit note The 6-SMD Gull Wing footprint sits flat on the solder paste for standard reflow. ## Sourcing posture — active, no LTB on record For a BOM cost engineer: the surface-mount reel variant (SR2) is the most widely stocked format; the through-hole CNY17F3M is a pin-compatible alternative.","metaTitle":"CNY17F3SR2M onsemi Optoisolator – 4170Vrms","metaDescription":"onsemi CNY17F3SR2M: single-channel DC-input transistor-output optocoupler, 4170Vrms isolation, 100–200% CTR at 10mA, -40°C to 100°C, 6-SMD Gull Wing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Product Status":"Active","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"CNY17F3","Voltage - Isolation":"4170Vrms","Vce Saturation (Max)":"400mV","Operating Temperature":"-40°C ~ 100°C","Rise / Fall Time (Typ)":"4µs, 3.5µs (Max)","Voltage - Output (Max)":"70V","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)":"1.35V","Turn On / Turn Off Time (Typ)":"2µs, 3µs","Current - DC Forward (If) (Max)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7500","priceTiers":[{"qty":1,"price":"$0.75000","currency":"USD"},{"qty":10,"price":"$0.48700","currency":"USD"},{"qty":100,"price":"$0.31890","currency":"USD"},{"qty":1000,"price":"$0.25179","currency":"USD"},{"qty":2000,"price":"$0.23501","currency":"USD"},{"qty":5000,"price":"$0.22661","currency":"USD"},{"qty":10000,"price":"$0.22326","currency":"USD"},{"qty":25000,"price":"$0.21822","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dbff72ad709f03fb6695b1cadd7ed9fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F3SR2M/alternatives.json"},"ai":{"faq":[{"question":"Can CNY17F3SR2M replace the through-hole CNY17F3M?","answer":"Electrically they are identical — same CTR range, same isolation voltage, same switching speeds. The difference is package: CNY17F3SR2M is surface-mount Gull Wing (6-SMD) on tape-and-reel; CNY17F3M is through-hole DIP-6 in tube. If your board has DIP-6 holes, the through-hole part is a drop-in. If your board is reflow-only, use the SR2 variant."},{"question":"What is the closest functional second-source for CNY17F3SR2M?","answer":"The CNY17F4SR2VM is the next CTR bin up — it guarantees 200% to 400% CTR at 10mA.

The CNY17F2SR2M is the lower CTR bin (63% to 125%)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/CNY17F3SR2M","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/CNY17F3SR2M when reusing this data.
