It provides 4170Vrms galvanic isolation between a DC input LED and a phototransistor output, with a current transfer ratio (CTR) range of 63% to 125% at a forward current of 10 mA. The 4170Vrms isolation rating means this part can withstand a 4.17 kV transient between input and output for 1 minute per UL 1577 — sufficient for reinforced insulation in mains-connected industrial PSUs, motor drives, and PLC digital input modules where the field side may see line transients. A wider CTR bin would require more margin in the pull-up resistor value. Output rating: 70 V Vce max and 50 mA continuous collector current — this covers 5 V and 24 V logic rails with headroom, and the 400 mV Vce saturation at 10 mA ensures the output pulls low enough to drive TTL or CMOS inputs without a level shifter. Switching speed: 2 µs turn-on, 3 µs turn-off typical, with 4 µs rise and 3.5 µs fall max — adequate for 10-100 kHz PWM feedback loops and 1-10 ms PLC scan cycles, but not for high-speed isolated data links above 100 kbps. ## Temperature range and deployment context The through-hole DIP package (0.300-inch body) is hand-solderable and survives rework cycles without moisture sensitivity level concerns. onsemi lists the CNY17F2VM as Active (current production).","metaTitle":"onsemi CNY17F2VM Optoisolator, 4170Vrms, 63-125% CTR, 6-DIP","metaDescription":"onsemi CNY17F2VM single-channel transistor-output optocoupler. 4170Vrms isolation, 63-125% CTR at 10mA, -40 to 100°C.
