Rated for 4170 Vrms isolation, it provides galvanic separation between input and output circuits in industrial signal-conditioning, PLC digital inputs, and motor-drive feedback paths where safety isolation is required. ## Switching and output ratings Typical turn-on time is 2 µs and turn-off time is 3 µs, with rise and fall times of 4 µs and 3.5 µs respectively — fast enough for 10–50 kHz digital signals in sensor interfaces and encoder feedback lines. The output transistor can handle up to 70 V across the collector-emitter and sink 50 mA continuous, with a maximum saturation voltage of 400 mV at rated current — sufficient to drive a 5 V logic input or a low-power relay coil. Forward voltage is typically 1.35 V, and the LED can be driven with up to 60 mA DC forward current; the wide CTR range means the input drive can be set conservatively at 10 mA while still guaranteeing output saturation. ## Package and temperature grade Housed in a 6-SMD gull-wing package (supplier device package 6-SMD), it is suited for reflow soldering and automated pick-and-place assembly.","metaTitle":"onsemi CNY173SR2VM Optoisolator, 4170Vrms, 1-Ch","metaDescription":"onsemi CNY173SR2VM optoisolator: 1-channel, DC input, transistor output, 4170Vrms isolation, 100-200% CTR, -40 to 100°C.
