Vishay, SFH690DT Phototransistor Output Optocoupler, Surface Mount, 8-Pin SOP

The Vishay SFH690DT family has a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a 4 pin 100 mil lead pitch miniflat package. It features a high current transfer ratio, low coupling capacitance, and high isolation voltage.
