Quantities are lot-specific and confirmed at RFQ — no stock-holding claim is made here. ## 7500Vpk isolation and CTR window Rated for 7500Vpk isolation, this optoisolator provides reinforced galvanic separation between the DC input and the transistor output stage — suitable for medical equipment, industrial PSU feedback loops, and high-voltage monitoring where the isolation barrier must withstand transient surges without breakdown. This bounded CTR window means the optocoupler's gain is predictable across the production spread — the downstream comparator or logic input sees a consistent collector current for a given forward current, simplifying the bias resistor calculation. ## Switching speed and output drive Rise and fall times are 1µs and 2µs typical; turn-on and turn-off times are 2µs and 3µs typical. This places the CNY172FR2VM in the medium-speed class for optocouplers — adequate for 50/60 Hz line-sync sampling, relay-drive gating, and low-speed digital isolation up to roughly 100 kbit/s. The output transistor is rated for 70V Vce(max) and 50mA continuous collector current. With a Vce(sat) of 400mV max at the rated current, the on-state voltage drop stays low enough to drive a 5V logic input directly through a pull-up resistor. ## 6-SMD gull wing footprint Housed in a 6-SMD gull-wing package (supplier device package 6-SMD), the part is intended for surface-mount assembly. The gull-wing leads provide a visible solder joint for AOI inspection and allow some thermal stress relief between the package body and the board. The forward voltage is 1.35V typical at If=10mA, and the absolute maximum forward current is 60mA.","metaTitle":"onsemi CNY172FR2VM Optoisolator, 7500Vpk, 6-SMD","metaDescription":"onsemi CNY172FR2VM optoisolator, 7500Vpk isolation, 63-125% CTR at 10mA, 6-SMD gull wing.
