Key transfer characteristics: current transfer ratio (CTR) is guaranteed between 160% and 320% at a forward current of 10 mA. This means the output transistor can sink at least 16 mA with 10 mA LED drive — sufficient to pull a logic input low or drive a low-power relay coil directly. Output side ratings: maximum collector-emitter voltage of 70 V and continuous output current of 50 mA per channel. Typical switching speeds are 1 µs rise and 2 µs fall, with turn-on/turn-off times of 2 µs and 3 µs respectively — fast enough for 100 kHz signal isolation in most industrial control interfaces. Operating temperature spans -55°C to 100°C, covering industrial and some military/aerospace ambient conditions. The 6-SMD gull-wing footprint is common for optocouplers and mates with standard SOIC-6 land patterns. onsemi has marked the CNY17F4SD as Obsolete. No official successor or pin-compatible replacement is listed in the current record. This part is no longer available through standard authorized distribution channels. Each lot is verified for authenticity and traceability before shipment. ## Package and board-fit note Supplied in Tape & Reel (TR) format, the CNY17F4SD is ready for automated pick-and-place assembly. The 6-SMD gull-wing leads are coplanar and solderable with standard reflow profiles for SOIC-6 packages. The supplier device package is designated 6-SMD — the same 7.5 mm × 9.5 mm body as the standard DIP-6 footprint but with formed gull-wing leads for surface mounting. No through-hole adapter is needed for SMD boards.","metaTitle":"onsemi CNY17F4SD Optoisolator, 5300Vrms, 160-320% CTR, 6-SMD","metaDescription":"onsemi CNY17F4SD single-channel transistor output optocoupler. 5300Vrms isolation, 160-320% CTR range, 6-SMD gull wing.
