It provides 5300 Vrms galvanic isolation between a DC input LED and a phototransistor output — a common choice for breaking ground loops in industrial PLC digital inputs, motor drive feedback, and isolated serial interfaces. The current transfer ratio (CTR) is specified at 63% minimum and 125% maximum when the LED is driven at 10 mA — this spread tells you the output transistor's collector current will be between 6.3 mA and 12.5 mA for that input condition. A tight CTR bin like this (the '230' suffix) makes it easier to design the pull-up resistor and guarantee the logic threshold across temperature and unit-to-unit variation. Output side: the phototransistor can sink up to 50 mA continuous and block 70 V across the collector-emitter. Saturation voltage is 300 mV max at the rated current — low enough to drive a 5 V logic input directly without a second transistor. Switching is modest: 1 µs rise, 2 µs fall typical, with turn-on/turn-off times of 2 µs and 3 µs respectively. That suits 10-100 kHz isolated data or PWM signals, not high-speed digital buses. No pin-compatible direct replacement from onsemi has been announced, so a board redesign may be needed if the supply window closes. ## Temperature grade and environment Rated for -55°C to +100°C operating ambient — the full industrial temperature range with margin into military cold. The 6-DIP through-hole package handles wave soldering and is field-replaceable without hot air. The 5300 Vrms isolation rating (1-minute test) meets reinforced insulation requirements for mains-isolated circuits per IEC 60950-1 and UL 1577.","metaTitle":"onsemi CNY17F2300W Optoisolator, 5300Vrms, 63-125% CTR","metaDescription":"onsemi CNY17F2300W single-channel transistor-output optocoupler, 5300 Vrms isolation, 63-125% CTR at 10 mA, 6-DIP through-hole.","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":"Through Hole","Package / Case":"6-DIP (0.400\\\", 10.16mm)","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-DIP","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":"$0.2060","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e34b4a420dd134390615c9fed8bb5f31.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F2300W/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the CNY17F2300W and get a price?","answer":"The CNY17F2300W is sourced through independent distribution channels.
