The current transfer ratio spans 100% to 200% at a forward current of 10 mA. ## Parametric boundaries for BOM fit Output transistor is rated for a maximum collector-emitter voltage of 30 V and continuous output current of 50 mA per channel. The Vce saturation is 400 mV maximum. Operating temperature range is -40°C to 85°C, which covers most industrial control cabinets, outdoor telecom shelters, and HVAC panels. If the application sees sustained ambient above 85°C, consider the FOD817ASD (rated to 110°C) — though its CTR and package differ.","metaTitle":"FOD2712AR2 onsemi Optoisolator – 2500Vrms, 8-SOIC, Active","metaDescription":"onsemi FOD2712AR2: single-channel DC-input transistor-output optoisolator, 2500Vrms isolation, 100-200% CTR at 10mA, -40°C to 85°C, 8-SOIC.

This means at 10 mA LED drive the output transistor is guaranteed to sink at least 10 mA; the 200% ceiling tells you the maximum gain you need to budget for in the load resistor."},{"question":"What is the difference between FOD2712 and FOD2712AR2?","answer":"The suffix 'AR2' indicates Tape & Reel packaging.
