Fairchild Semiconductor MOC8021M, MOC8050M Photodarlington Optocoupler Datasheet
This document is a datasheet for the Fairchild Semiconductor MOC8021M and MOC8050M photodarlington optocouplers. These devices consist of a gallium arsenide infrared emitting diode coupled with a silicon darlington phototransistor, designed for applications requiring high current transfer ratios and improved noise immunity due to the lack of a base connection.
The datasheet provides absolute maximum ratings, electrical characteristics, and isolation ratings for both models. It includes typical performance curves for parameters such as forward voltage, current transfer ratio, and switching times, along with package dimensions for through-hole and surface mount configurations.
