The SFH617A-2 is a DIP-4 optocoupler with a GaAs infrared LED optically coupled to a silicon phototransistor, designed for signal transmission between electrically isolated circuits. It features a 5300 V RMS isolation voltage, a 70 V collector-emitter voltage rating, and a forward current maximum of 60 mA. The current transfer ratio (CTR) ranges from 63% to 125% at 10 mA forward current and 5 V collector-emitter voltage. It supports operating temperatures from -55°C to +110°C, with creepage and clearance distances of at least 8 mm for option 6 packaging. The device meets UL1577, cUL, IEC 60950, IEC 60065, and DIN EN 60747-5-5 safety standards. It has a low coupling capacitance of 0.4 pF and fast switching times, with turn-on and turn-off times of 4.2 μs typical under saturated conditions. The package is end-stackable with 2.54 mm pin spacing.
