SFH617A-4 Datasheet PDF - Vishay Semiconductor

●The SFH617A-4 is a 1-channel 4-pin Phototransistor Output Optocoupler features a high current transfer ratio, low coupling capacitance and high isolation voltage. This coupler has a GaAs infrared diode emitter, which is optically coupled to a silicon planar phototransistor detector. It is designed for signal transmission between two electrically separated circuits. The coupler is end-stackable with 2.54mm spacing. Creepage and clearance distances of >8mm. It is also suitable for AC adapter, PLC and game consoles.
