Current transfer ratio (CTR) is specified at 100% minimum and 200% maximum at If = 10 mA. This guarantees the output transistor saturates with a logic-level load when driven at 10 mA forward current, giving a clean digital signal across the isolation gap without overdriving the LED. Switching speed is moderate: 1 µs rise and 2 µs fall times, with turn-on at 2 µs and turn-off at 3 µs typical. This suits 10–100 kbps isolated data links, relay drivers, or PLC input isolation — not high-speed communication like I²C or CAN. ## Package, mounting, and temperature range Housed in a 6-SMD Gull Wing package (supplier device package 6-SMD), the CNY173FR2M is designed for reflow soldering on standard surface-mount footprints. The Gull Wing leads provide good coplanarity and visual solder-joint inspection. Operating temperature spans –40°C to 100°C, covering industrial and outdoor equipment environments. The output stage can handle up to 70 V and 50 mA continuous, enough to drive a small relay coil or a logic input directly. ## Lifecycle reality — obsolete, sourced per RFQ onsemi lists the CNY173FR2M as Obsolete.","metaTitle":"onsemi CNY173FR2M Optoisolator, 7500Vpk, 6-SMD Gull Wing","metaDescription":"onsemi CNY173FR2M optoisolator, 1-channel DC input, transistor output, 7500Vpk isolation, 100-200% CTR, 6-SMD Gull Wing.
