DESCRIPTION
The MOC8020 and MOC8021 are photodarlington-type optically coupled optocouplers. The devices have a gallium arsenide infrared emitting diode coupled with a silicon darlington phototransistor.

FEATURES
• High current transfer ratio
   -500% (MOC8020)
   -1000% (MOC8021)
• No base connection for improved noise immunity
• Underwriters Laboratory (UL) recognized File# E90700

APPLICATIONS
• Appliances, measuring instruments
• I/O interface for computers
• Programmable controllers
• Portable electronics
• Interfacing and coupling systems of
   different potentials and impedance
• Solid state relays
