NON BASE LEAD
OPTICALLY COUPLED ISOLATOR
PHOTODARLINGTON OUTPUT
MOC8020, MOC8021
DESCRIPTION
The MOC8020, MOC8021 series of optically
coupled isolators consist of an infrared light
emitting diode and NPN silicon photodarlington
in a standard 6pin dual in line plastic package
with the base pin unconnected.
