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.

Applications

• Appliances, Measuring Instruments

• I/O Interfaces for Computers

• Programmable Controllers

• Portable Electronics

• Interfacing and coupling systems of different potentials and impedances

• Solid State Relays
