MOC3021 Datasheet – Random Phase Optoisolator IC

213 views

Overview

The MOC3020 Series consists of gallium arsenide infrared emitting diodes, optically coupled to a silicon bilateral switch. To order devices that are tested and marked per VDE 0884 requirements, the suffix ”V” must be included at the end of the part number. VDE 0884 is a test option. They are designed for applications requiring isolated triac triggering.
