That spread gives the designer a predictable output current range without over-specifying the LED drive — the 200 mV Vce(sat) ceiling keeps the transistor in hard saturation across the CTR window. Rise and fall times are 4 µs and 3 µs typical, adequate for 10–20 kHz switching or digital signal isolation at moderate data rates. Lifecycle status is Active per onsemi. Operating temperature from -55°C to 110°C covers industrial and outdoor applications where commercial-grade optos would drift or latch.","metaTitle":"FOD817A3SD onsemi Optoisolator 5000Vrms Transistor Output","metaDescription":"FOD817A3SD onsemi optoisolator: 5000Vrms isolation, DC input, transistor output, 80-160% CTR at 5mA, -55°C to 110°C, 4-SMD Gull Wing.
