With a current transfer ratio (CTR) guaranteed between 100% and 200% at a forward current of 10 mA, the designer can size the LED drive resistor to ensure the output transistor saturates across the full CTR spread. The typical forward voltage is 1.2 V. The output transistor is rated for a maximum collector-emitter voltage of 70 V and can sink up to 50 mA continuous. Maximum Vce saturation is 400 mV, which keeps the on-state voltage drop low in logic-level interfaces. ## Industrial temperature range, active lifecycle The operating temperature range is -25°C to 85°C, which covers most commercial and light-industrial environments but excludes extended industrial or automotive applications. The device is ROHS3 compliant. ## Tube packaging, surface-mount footprint For automated pick-and-place, plan for tube feeding or request a reel alternative if available. The 8-SOIC footprint (3.90 mm width, 0.154-inch pitch) is industry-standard and matches common land patterns.","metaTitle":"FOD2742BV onsemi Optoisolator","metaDescription":"onsemi FOD2742BV optocoupler: 2500Vrms isolation, transistor output, CTR 100%–200% at 10 mA, -25°C to 85°C, 8-SOIC.
