Current transfer ratio spans 63% minimum to 125% maximum at 10 mA forward current — a wide enough window that the logic threshold on the output side stays well-defined without requiring tight binning of the LED. The transistor-with-base output lets you add an external base resistor to trade switching speed against gain, useful when driving a slow opto-coupler into a fast PLC input. Rise and fall times are 4 µs and 3.5 µs typical respectively, with turn-on at 2 µs and turn-off at 3 µs — adequate for 100 kHz data rates but not for high-speed isolated communication like I²C or CAN. The 70 V output breakdown and 50 mA continuous output current cover most logic-level and low-power relay drive applications. The base part number CNY172 covers multiple CTR and packaging variants; the VM suffix denotes the tube-packaged, ROHS3-compliant version. ## Package and temperature grade The 7.62 mm row spacing provides adequate creepage for the 4170 Vrms rating; keep the copper keep-out zone under the body per the recommended PCB layout to maintain isolation distance.","metaTitle":"onsemi CNY172VM Optoisolator, 4170 Vrms, 6-DIP","metaDescription":"onsemi CNY172VM optoisolator: 4170 Vrms isolation, 63-125% CTR, transistor with base output, -40 to 100°C.
