Product Description
Product Overview
The VOS628A series is an optocoupler featuring a GaAs infrared emitting diode optically coupled to a silicon planar phototransistor. Housed in a 4-pin SSOP-4 mini-flat package with a 50 mil lead pitch, it offers high current transfer ratio at low input current, low coupling capacitance, and high isolation voltage. Designed for signal transmission between electrically separated circuits, it is suitable for applications in telecom, industrial controls, battery-powered equipment, office machines, and programmable controllers.
