No successor or cross-reference is on file from the manufacturer. Sourcing runs through independent distribution — quantities and pricing confirmed at RFQ against your BOM line. ## Isolation and signal transfer specs Rated for 4170Vrms isolation — this covers reinforced insulation requirements in mains-isolated feedback loops, IGBT gate drive supplies, and medical equipment barrier applications where 3750Vrms is the minimum and 4170Vrms adds margin. Current transfer ratio (CTR) is guaranteed between 40% and 80% at a forward current of 10 mA. Output side handles up to 70V collector-emitter and 50 mA continuous current — enough to drive a small relay coil, a PLC digital input, or a level shifter in a 24V industrial control loop. ## Package and temperature grade Housed in a 6-SMD gull wing package — the same footprint as the industry-standard DIP-6 surface-mount optocoupler. The gull wing leads provide visual solder joint inspection and rework access, unlike a flat-lead or BGA package. Suitable for outdoor telecom cabinets, motor drive control boards, and HVAC controller PCBs where the internal enclosure temperature stays below 85°C. ## Switching speed for the application Typical turn-on time is 2 µs, turn-off 3 µs, with rise/fall times of 4 µs and 3.5 µs max. That limits the useful data rate to about 100 kbps — fine for 50/60 Hz zero-crossing detection, slow digital isolator replacement, or status feedback from a contact closure. Not suited for high-speed serial buses like SPI or CAN.","metaTitle":"onsemi CNY171FR2VM Optoisolator, 4170Vrms, 6-SMD","metaDescription":"onsemi CNY171FR2VM obsolete optoisolator, 4170Vrms isolation, 40-80% CTR at 10mA, 70V output, 6-SMD gull wing.
