Current transfer ratio is specified as 160% min and 320% max at If=10mA — this band tells you the output current you can expect for a given forward current, which sets the load resistor and logic threshold in the receiving circuit. With a Vce saturation of 300mV max and output voltage rated to 70V, the transistor side can drive a 50mA load directly — suitable for PLC digital inputs, relay coils, or level shifting across the isolation boundary. The operating temperature range of -55°C to 100°C covers industrial and some military-grade environments, but the obsolete status means new designs should evaluate a current-production optoisolator from the same or a compatible family. Housed in a 6-DIP (0.300\", 7.62mm) through-hole package with a supplier device package of 6-DIP — the standard 0.100-inch pitch DIP footprint that mates with breadboards, sockets, or soldered into a PCB. Delivered in tube packaging. Rise and fall times are 1µs and 2µs typical; turn-on and turn-off times are 2µs and 3µs typical — this switching speed is adequate for 100 kbps data rates or low-frequency signal isolation in industrial control loops.","metaTitle":"onsemi CNY17F4 Optoisolator, 5300Vrms, 6-DIP","metaDescription":"onsemi CNY17F4 optoisolator, 5300Vrms isolation, 160-320% CTR at 10mA, DC input, transistor output, 6-DIP.
