The through-hole footprint is breadboard- and perfboard-friendly — no reflow profile needed, just a soldering iron and a clean pad. ## Key parametrics for the BOM line Single-channel optoisolator with a DC input LED (1.35 Vf typical at 10 mA) and a phototransistor output rated for 70 V max and 50 mA continuous. The current transfer ratio (CTR) is guaranteed between 160% and 320% at 10 mA forward current — a wide enough window to tolerate LED ageing and still drive a logic input or a low-power relay. Isolation rating is 5300 Vrms — sufficient for reinforced isolation in mains-connected circuits (power supplies, motor drives, PLC I/O) where the working voltage stays under 250 Vrms. Switching speed is modest: 1 µs rise / 2 µs fall typical, with turn-on/turn-off times of 2 µs / 3 µs. Not a candidate for high-speed data links, but fine for 50/60 Hz zero-cross detection, status feedback, or slow digital signals.","metaTitle":"onsemi CNY17F4W Optoisolator, 5300Vrms, 6-DIP, Obsolete","metaDescription":"onsemi CNY17F4W optoisolator, 1-channel transistor output, 5300Vrms isolation, 160-320% CTR at 10mA.
