MOC8021 - PHOTODARLINGTON OPTOCOUPLERS

Download the MOC8021 datasheet PDF. This datasheet also covers the MOC8020 variant, as both devices belong to the same photodarlington optocouplers family and are provided as variant models within a single manufacturer datasheet.

General 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.

PIN 1 ID.

Key Features

  • High current transfer ratio 6 -500% (MOC8020) -1000% (MOC8021).
  • No base connection for improved noise immunity.
  • Underwriters Laboratory (UL) recognized File# E90700.
