The FOD2712AV: That isolation rating is typical for basic insulation in industrial control or power-supply feedback loops where the safety barrier must withstand 2500Vrms for one minute per UL 1577 — enough for reinforced insulation in many 240VAC applications. The current transfer ratio (CTR) is specified at 100% minimum and 200% maximum when the LED is driven at 10mA. This means the output transistor can sink at least as much current as the LED draws — a 10mA input yields at least 10mA at the output — giving the designer a predictable gain window for logic-level translation or isolated feedback without needing to overdrive the LED. The output is rated for 30V maximum and 50mA continuous per channel — sufficient for driving a downstream gate, PLC input, or low-power relay coil.
Housed in an 8-SOIC package (3.90mm body width) with a surface-mount footprint, the FOD2712AV ships in tube packaging. The 8-SOIC outline matches industry-standard SOIC-8 land patterns, so no special footprint is needed — it drops into the same pads as many generic transistor-output optoisolators.
