This part is sourced through independent distribution channels — quantities are lot-specific and confirmed at RFQ. ## Isolation and CTR — what they mean for the BOM Rated for 5300Vrms isolation — this is the reinforced insulation level for mains-isolated interfaces in industrial PSUs, motor drives, and PLC digital inputs. The 6-DIP package provides the creepage distance to sustain that rating across the barrier. Current transfer ratio spans 63% minimum to 125% maximum at If=10mA. The 63% floor means the output transistor can sink at least 6.3mA with 10mA LED drive — sufficient to pull a 5V logic input low through a 680Ω pull-up. The 125% ceiling ensures the part does not saturate the receiver's input stage at the same drive current. Output transistor is rated for 70V Vce max and 50mA continuous collector current — suitable for switching 24V PLC inputs or driving a low-current relay coil directly. Vce saturation is 300mV max, keeping the on-state voltage drop well below the logic-low threshold of a 5V TTL input. ## Switching speed and temperature range Turn-on and turn-off times are 2µs and 3µs typical respectively; rise and fall times are 1µs and 2µs. This limits the usable data rate to roughly 100 kbit/s in a digital isolator application — adequate for 24V DC fieldbus signals or slow PWM updates, but not for high-speed serial links. Operating temperature spans -55°C to 100°C — the full industrial range. The 100°C upper limit covers most factory-floor and outdoor cabinet environments, though the LED forward current may need derating above 85°C to stay within the 100mA absolute maximum.","metaTitle":"onsemi CNY17F2 Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY17F2 single-channel transistor output optocoupler. 5300Vrms isolation, 63-125% CTR at 10mA, -55 to 100°C.","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 (0.300\\\", 7.62mm)","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":"$0.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e34b4a420dd134390615c9fed8bb5f31.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY17F2/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the CNY17F2?","answer":"The base product number is CNY17, which shares the same 6-DIP footprint and pinout.
