Description

The MOC223M consists of a gallium arsenide infrared

emitting diode optically coupled to a monolithic silicon

photodarlington detector, in a surface mountable, small

outline, plastic package. The MOCD223M is a dual-

channel version of the MOC223M. They are

ideally

suited for high density applications, and eliminates the

need for through the board mounting.
