The onsemi CNY17F4VM is a single-channel optoisolator with a DC input and a phototransistor output, housed in a 6-DIP (0.300", 7.62mm) through-hole package supplied in bulk. The output transistor can switch up to 70V and sink 50mA continuous, with a maximum Vce saturation of 400mV at rated current — adequate for driving a PLC input or a low-power relay coil directly. Typical switching speeds are 2µs turn-on and 3µs turn-off (with 4µs rise and 3.5µs fall max), placing this part in the medium-speed class for 50/60Hz line isolation or slow digital signals. Operating temperature spans -40°C to 100°C, covering industrial enclosures and outdoor telecom cabinets without derating.
