The H11D1 and H11D2 consist of gallium arsenide infrared emitting diodes optically coupled to high voltage, silicon, phototransistor detectors in a standard 6–pin DIP package. They are designed for high voltage applications and are particularly useful in copy machines and solid state relays.
   
• To order devices that are tested and marked per VDE 0884 requirements, the
    suffix ”V” must be included at end of part number. VDE 0884 is a test option.
