The MOC8020 and MOC8021 devices consist of a gallium arsenide infrared emitting diode optically coupled to a monolithic silicon photodarlington detector. The chip to Pin 6 base connection has been eliminated to improve the device’s output performance in higher noise environments.
• No Base Connection for Improved Noise Immunity
• Higher Sensitivity to Low Input Drive Current
• 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.
