(2.54 mm) spacing Material categorization: For definitions of compliance please see www.vishay.com/doc?9992 DESCRIPTION The C rated VOM68A has a GaAs infrared emitting diode emitter, which is optically coupled to a silicon planar phototransistor detector, and is incorporated in a 4 pin mil lead pitch miniflat package. It features a high current transfer ratio with low input current, low coupling capacitance, and high isolation voltage. These coupling devices are designed for signal transmission between two electrically separated circuits.
