Current transfer ratio spans 160% to 320% at a forward current of 10 mA — the min CTR guarantees that a 10 mA LED drive produces at least 16 mA of collector current in the output phototransistor, which sets the pull-down capability at the load side. Output transistor rated for 70 V max across the collector-emitter path and 50 mA continuous output current — sufficient for driving logic-level inputs, relay coils, or small DC loads in isolated feedback paths. ## Switching speed and temperature envelope Typical turn-on time of 2 µs and turn-off time of 3 µs, with rise/fall times of 4 µs and 3.5 µs respectively — this switching speed suits 10-100 kHz isolated communication (e.g., IGBT gate-drive feedback, isolated SPI) where the propagation delay and edge rates stay within the timing budget.","metaTitle":"onsemi CNY174SVM Optoisolator, 4170Vrms, 160-320% CTR","metaDescription":"onsemi CNY174SVM Optoisolator: 1-ch, 4170Vrms isolation, 160-320% CTR, 70V output, 6-SMD Gull Wing.
