It provides 4170Vrms galvanic isolation between a DC-input LED and the phototransistor, sufficient for basic functional isolation in industrial control, power supply feedback, and signal-interface circuits where the primary-to-secondary barrier must withstand transient overvoltages without breakdown. ## CTR floor and ceiling at 10 mA With a 70 V output ceiling and 50 mA continuous output current, the part drives logic inputs, relays, or low-side loads directly from the isolated side. ## Switching speed and temperature range Typical turn-on time is 2 µs and turn-off time 3 µs, with rise/fall times of 4 µs and 3.5 µs respectively — these numbers suit 10–100 kHz switching applications like isolated gate drive or serial data coupling.","metaTitle":"onsemi CNY172SR2M Optoisolator, 4170Vrms, 6-SMD Gull Wing","metaDescription":"onsemi CNY172SR2M optoisolator: 4170Vrms isolation, 63-125% CTR at 10mA, 70V output, 6-SMD Gull Wing.
