5000Vrms isolation — the safety barrier your BOM needs
CTR bin A: 80%–160% at 5 mA — no guesswork on drive margin
Current transfer ratio is binned: minimum 80%, maximum 160%, both specified at If = 5 mA. 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.
