The SFH617A series is a high-reliability optocoupler with phototransistor output, designed for signal transmission between electrically isolated circuits. It features a GaAs infrared LED optically coupled to a silicon phototransistor in a DIP-4 package with 2.54 mm pin spacing. The device supports an isolation test voltage of 5300 V RMS, a collector-emitter voltage of 70 V, and an operating temperature range from -55 °C to +110 °C. It meets UL1577, cUL, and VDE safety standards. The SFH617A-2 variant has a current transfer ratio ranging from 63% to 125% at 10 mA forward current and 5 V collector-emitter voltage. This part provides fast switching times and low coupling capacitance, suitable for applications such as SMPS, PLC, and factory automation.
