The DC input drives an infrared LED (typical forward voltage 1.25 V, max forward current 75 mA), and the transistor output can switch up to 32 V at 50 mA per channel. With a current transfer ratio (CTR) guaranteed between 63% and 125% at a forward current of 10 mA, this part provides a predictable gain window for the isolated signal path. ## Temperature range and switching speed for harsh environments The transistor output's typical rise time is 2.4 µs and fall time 2.7 µs, with turn-on and turn-off times of 5 µs and 3 µs respectively. That puts the practical switching ceiling around 100 kHz for a 50% duty-cycle square wave; for faster isolated data paths, a logic-output optocoupler would be a better fit. The 300 mV max Vce saturation at the rated output current keeps power dissipation low in the output stage. No official successor or second-source cross-reference appears in the Vishay documentation; if you need a pin-compatible alternate for dual-sourcing, a parametric search across Vishay's own CNY65 family or a direct inquiry with the factory would be the next step.","metaTitle":"Vishay CNY65A Optoisolator, 8200 Vrms, Transistor Output","metaDescription":"Vishay CNY65A optocoupler with 8200 Vrms isolation, transistor output, 63-125% CTR at 10 mA, -55°C to 85°C range.
