Rated for 5300 Vrms isolation, it provides basic galvanic separation between a DC input (up to 100 mA forward current) and a 70 V, 50 mA output stage. Current transfer ratio spans 63% to 125% at 10 mA forward current — the 2:1 min/max spread means the CTR bin is tight enough to avoid gain-matching issues in a multi-channel feedback loop. ## Switching speed and temperature range Typical turn-on time is 2 µs and turn-off time 3 µs, with rise and fall times of 1 µs and 2 µs respectively — adequate for 50/60 Hz mains sensing or slow digital isolation below 100 kHz. The part is sourced to order against the BOM line — no stock-holding claim.","metaTitle":"onsemi CNY17F23S Optoisolator, 5300Vrms, 63-125% CTR, 6-SMD","metaDescription":"onsemi CNY17F23S optoisolator, 1-channel transistor output, 5300Vrms isolation, 63-125% CTR at 10mA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tube","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":"5300Vrms","Vce Saturation (Max)":"300mV","Operating Temperature":"-55°C ~ 100°C","Rise / Fall Time (Typ)":"1µs, 2µs","Voltage - Output (Max)":"70V","Supplier Device Package":"6-SMD","Current - Output / Channel":"50mA","Current Transfer Ratio (Max)":"125% @ 10mA","Current Transfer Ratio (Min)":"63% @ 10mA","Voltage - Forward (Vf) (Typ)":"1.35V","Turn On / Turn Off Time (Typ)":"2µs, 3µs","Current - DC Forward (If) (Max)":"100 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e34b4a420dd134390615c9fed8bb5f31.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F23S/alternatives.json"},"ai":{"faq":[{"question":"How can I order the CNY17F23S or check availability?","answer":"The CNY17F23S is obsolete per onsemi's lifecycle status."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/onsemi/CNY17F23S","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/onsemi/CNY17F23S when reusing this data.
