Current transfer ratio spans 80% to 160% at a forward current of 5 mA, giving the designer a guaranteed minimum CTR for logic-level interfacing — the 200mV max Vce saturation keeps the output transistor's voltage drop low enough to drive a downstream gate or PLC input without a pull-up resistor adjustment. The -55°C to 110°C operating range covers industrial and automotive ambient extremes — the 4µs rise and 3µs fall times support switching frequencies up to roughly 100 kHz before the output waveform degrades. Housed in a 4-DIP (0.400\", 10.16mm) through-hole package, the FOD817AW mounts directly into a standard 0.100-inch pitch DIP socket or solders into plated through-holes on a single- or double-sided PCB — no special footprint beyond the standard 7.62 mm row spacing. The DC input and transistor output configuration is the most common optocoupler topology: the LED on the input side switches the phototransistor on the output side, providing 5000Vrms of galvanic isolation between the two circuits.","metaTitle":"onsemi FOD817AW Optoisolator, DC Input, Transistor Output","metaDescription":"onsemi FOD817AW optoisolator, 5000Vrms isolation, 80-160% CTR at 5mA, -55 to 110°C.
