The current transfer ratio (CTR) is specified at 100% minimum and 200% maximum when the LED is driven with 10 mA forward current — this bracket determines the minimum input current needed to guarantee the output transistor saturates into the load, which directly sets the LED drive resistor value in the design. Turn-on time is 2 µs typical, turn-off time 3 µs typical, with rise and fall times at 4 µs and 3.5 µs maximum respectively — this limits the usable data rate to low-speed digital signals or 50/60 Hz line-frequency feedback; it will not pass a 100 kHz PWM without pulse-width distortion. The output transistor can sink up to 50 mA continuous and withstand 70 V collector-emitter, with a saturation voltage of 400 mV maximum at the rated forward current — sufficient for driving a PLC input, a logic gate, or a relay coil through a base resistor. ## Package, temperature, and lifecycle — what changes when the part goes obsolete Housed in a 6-SMD Gull Wing package (supplier device package 6-SMD) for surface-mount assembly on a standard PCB footprint — the gull-wing leads provide visual solder-joint inspection access. Rated for continuous operation from -40°C to +100°C, covering industrial enclosure and outdoor telecom cabinet ambient conditions without derating.","metaTitle":"onsemi CNY17F3SR2M_F132 Optoisolator, 4170Vrms, Obsolete","metaDescription":"onsemi CNY17F3SR2M_F132 single-channel optoisolator, 4170Vrms isolation, DC input, transistor output, 6-SMD Gull Wing.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tape & Reel (TR)","Input Type":"DC","Output Type":"Transistor","Mounting Type":"Surface Mount","Package / Case":"6-SMD, Gull Wing","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"CNY17","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":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dbff72ad709f03fb6695b1cadd7ed9fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F3SR2M_F132/alternatives.json"},"ai":{"faq":[{"question":"Who supplies the CNY17F3SR2M_F132 and how is it quoted?","answer":"Sourced through independent distribution against an RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/CNY17F3SR2M_F132","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/CNY17F3SR2M_F132 when reusing this data.
