MCT2E, MCT2
OPTICALLY COUPLED ISOLATORS

Circuit

Features

2500 or 1500 V Isolation.
High DC Current Transfer Ratio.
Low Cost Dual-In-Line Package.

Description

The MCT2E, MCT2 are optically coupled isolators consisting of a Gallium Arsenide infrared emitting diode and an NPN silicon phototransistor mounted in a standard 6-pin dual-in-line package. Surface Mount Option Available.
All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a cumulative 0.65% AQL.
