PHOTODARLINGTON OPTOCOUPLERS (NO BASE CONNECTION)
MOC8020 MOC8021
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 |
6 |
-500% (MOC8020) |
