The 5300 Vrms isolation rating qualifies it for reinforced insulation in mains-referenced circuits — enough to meet IEC 60950-1 and IEC 62368-1 creepage requirements for basic isolation up to 300 V working voltage. The transistor output is rated for 70 V collector-emitter and 50 mA continuous current, with a Vce(sat) of 300 mV max at the rated drive. The 63% to 125% CTR range at 10 mA forward current gives a predictable gain window for logic-level translation across the isolation barrier. Switching speed is specified at 1 µs rise and 2 µs fall typical, with turn-on and turn-off times of 2 µs and 3 µs respectively. This suits it for 100 kHz-range signal isolation — below that the propagation skew is negligible for most PLC digital input and feedback circuits. onsemi has marked the CNY17F2W as Obsolete. No official successor or pin-compatible second-source is recorded in the manufacturer's lifecycle documentation. The -55°C to +100°C operating temperature range covers industrial and some automotive under-hood environments. The DC input type means it switches on a forward current — no AC zero-crossing circuitry — so it works with standard microcontroller GPIO or logic outputs driving the LED.","metaTitle":"onsemi CNY17F2W Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY17F2W optoisolator, 1-channel, transistor output, 5300Vrms isolation, 63-125% CTR @ 10mA.
