The output is a phototransistor, not a logic gate, so the designer controls the pull-up and the switching threshold. With a 63–125 % current transfer ratio at 10 mA forward current, the CTR bin is tight enough to avoid overdriving a 5 V logic input or leaving it marginal at cold temperature. ## Switching speed and saturation — the timing numbers that matter Turn-on time is 2 µs typical, turn-off 3 µs typical, with rise and fall times of 4 µs and 3.5 µs max. That puts the usable switching frequency around 50–60 kHz for a clean pulse train — fast enough for a PLC input or a gate-drive feedback path, not fast enough for a switching power supply loop. Vce(sat) is 400 mV maximum at the output transistor. That means the collector can pull a 5 V logic input below 0.8 V with margin, even with a 50 mA output load. The 70 V output breakdown gives headroom for 24 V industrial rails or a 48 V telecom bus. ## Temperature range and package — where it lives on the board Rated for –40 to 100 °C, the CNY17F2M covers the thermal envelope of a factory-floor PLC or an outdoor telecom enclosure. The through-hole 6-DIP (0.300\", 7.62 mm) footprint is a standard 300-mil DIP — no exotic pad pattern, no reflow profile to tune. The input is DC only — there is no AC-input LED, so the forward current must be unidirectional. If the application needs AC line sensing, look at a zero-crossing or AC-input opto instead. The BOM line is stable for the foreseeable production horizon. The base product number is CNY17F, so the same die and package family spans multiple CTR bins. The F2 suffix selects the 63–125 % range; the F3 (100–200 %) is a drop-in swap if the design needs more gain. The SR2 suffix variant is the same die in a surface-mount package for reflow assembly.","metaTitle":"CNY17F2M onsemi Optoisolator – 4170 Vrms, 6-DIP, Active","metaDescription":"onsemi CNY17F2M single-channel transistor-output optocoupler. 4170 Vrms isolation, 63–125 % CTR at 10 mA, –40 to 100 °C.

That bin is tighter than the standard CNY17F (40–80 %) or the F3 (100–200 %), so it suits designs that need a predictable gain without overdrive on the output side."},{"question":"Can CNY17F2M be used with AC input?","answer":"No. The input type is DC only — the LED is a single diode, not an anti-parallel pair. For AC line sensing, use an optocoupler with two back-to-back LEDs or a zero-crossing detector."},{"question":"When sourcing CNY17F2M, what is the closest functional second-source — CNY17F2TVM?","answer":"The CNY17F2TVM shares the same CTR bin (63–125 %), the same 4170 Vrms isolation, and the same through-hole 6-DIP package.
