Vishay, VOL628A Phototransistor Output Optocoupler, Surface Mount, 4-Pin LSOP

The Vishay Optocoupler has two GaAs infrared emitting diodes, which are optically coupled to a silicon planar phototransistor detector, and are incorporated in a 4 pin LSOP wide body package. It features a high current transfer ratio, low coupling capacitance, and high isolation voltage. The coupling device is designed for signal transmission between two electrically separated circuits.
