Its 4170Vrms isolation rating covers the 250V working voltage common in motor-drive feedback, PLC digital inputs, and AC-mains-referenced sensor interfaces. The current transfer ratio spans 63% to 125% at 10mA forward current, giving enough gain headroom to drive a 5V logic input or a low-power relay coil without an external transistor stage. ## Through-hole DIP with transistor-base output Housed in a 6-DIP (0.300\", 7.62mm) through-hole package, the CNY172M mates with standard 0.100-inch pitch sockets or wave-solder pads. The base pin on the output side allows the designer to add a base resistor or a speed-up capacitor for switching applications. Typical turn-on and turn-off times are 2µs and 3µs respectively, with rise/fall times of 4µs and 3.5µs — fast enough for 10–20 kHz PWM isolation or serial data at moderate baud rates. The output transistor can sink up to 50mA continuous at a maximum Vce of 70V, with a saturation voltage of 400mV typical — adequate for driving a 24V PLC input module or a 5V CMOS gate. ## Active lifecycle with industrial temperature range ROHS3 compliance is confirmed, so the part meets current EU and global restriction-of-hazardous-substances requirements for new designs.","metaTitle":"CNY172M onsemi Optoisolator 4170Vrms 6-DIP Active","metaDescription":"onsemi CNY172M optoisolator: 4170Vrms isolation, 63%-125% CTR at 10mA, DC input, transistor with base output, -40°C to 100°C, 6-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Optoisolators"],"specifications":{"Mfr":"onsemi","Series":"-","Package":"Tube","Input Type":"DC","Output Type":"Transistor with Base","Mounting Type":"Through Hole","Package / Case":"6-DIP (0.300\\\", 7.62mm)","Product Status":"Active","lifecycle_stage":"eol_hot","Number of Channels":"1","Base Product Number":"CNY172","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-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)":"60 mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6200","priceTiers":[{"qty":1,"price":"$0.64000","currency":"USD"},{"qty":10,"price":"$0.42200","currency":"USD"},{"qty":100,"price":"$0.27920","currency":"USD"},{"qty":1000,"price":"$0.21555","currency":"USD"},{"qty":2000,"price":"$0.19478","currency":"USD"},{"qty":5000,"price":"$0.18179","currency":"USD"},{"qty":10000,"price":"$0.17530","currency":"USD"},{"qty":25000,"price":"$0.17270","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/dbff72ad709f03fb6695b1cadd7ed9fe.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CNY172M/alternatives.json"},"ai":{"faq":[{"question":"Is the CNY172M RoHS compliant?","answer":"Yes, onsemi lists the CNY172M as ROHS3 compliant, meaning it meets the current EU RoHS directive without exemptions."},{"question":"What is the input type of the CNY172M?","answer":"The input is DC only — the LED is driven by a DC forward current up to 60mA, with a typical forward voltage of 1.35V.
