Availability is confirmed per RFQ through independent distribution channels; quantities are lot-specific. ## Isolation and signal transfer Rated for 4170Vrms isolation between input and output — this covers reinforced insulation requirements in mains-referenced circuits such as industrial I/O modules, motor-drive feedback, and isolated power-supply loops. The 6-DIP package provides the creepage distance to sustain that voltage across the barrier. Current transfer ratio (CTR) is specified at 63% minimum to 125% maximum, tested at 10 mA forward current. That range tells you the output transistor's gain spread — a design must accommodate the full band so the downstream logic sees a valid high state even at the low end of the CTR bin. ## Output ratings and switching speed The phototransistor output is rated for 70 V maximum and 50 mA continuous current — suitable for driving logic inputs, small relays, or a DC bus up to that voltage. Turn-on time is 2 µs typical, turn-off 3 µs typical; rise and fall times are 4 µs and 3.5 µs max. That puts the usable switching frequency in the low tens of kilohertz — fine for 50/60 Hz line synchronisation, relay drivers, or slow digital isolation, but not for high-speed data links. ## Package and temperature range Housed in a 6-DIP (0.400-inch, 10.16 mm) through-hole package with a 2.54 mm pin pitch. The wide body provides the creepage needed for the 4170Vrms rating. Operating temperature spans -40°C to 100°C, covering industrial and commercial environments. Supplied in bulk tube — no tape-and-reel option, so pick-and-place requires a tube feeder or manual placement. The through-hole DIP footprint is standard and well-supported across assembly houses.","metaTitle":"onsemi CNY17F2TM Optoisolator, 4170Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY17F2TM optoisolator, 1-channel DC-input transistor output, 4170Vrms isolation, 63-125% CTR.
