The IL251 is a single-channel, bidirectional optocoupler with a phototransistor output and base connection, designed for AC signal detection and monitoring. It features an industry-standard 6-pin DIP package with a footprint of 7.62 mm × 10.16 mm. The device has a minimum current transfer ratio (CTR) of 20% at ±10 mA LED current and 10 V collector-emitter voltage. It provides galvanic isolation with a maximum rated withstanding isolation voltage of 4420 Vrms and a transient isolation voltage of 10,000 Vpeak. The optocoupler meets UL1577, cUL, CSA, BSI, and VDE safety standards, and is rated for operation from -55 °C to +100 °C with a maximum total power dissipation of 250 mW. Reverse polarity protection is built into the input. Collector-emitter saturation voltage is ≤0.4 V at ±16 mA input and 2 mA output current.
