The Vishay Optocoupler consisting of a gallium arsenide infrared emitting diode optically coupled to a silicon planar phototransistor detector in a plastic plug-in DIP-6 package. The coupling device is suitable for signal transmission between two electrically separated circuits. The potential difference between the circuits to be coupled is not allowed to exceed the maximum permissible reference voltages. Isolation test voltage, 5000 VRMS
No base terminal connection for improved common mode interface immunity
Long term stability
Industry standard dual-in-line package
