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