MCA255 - Optically-Coupled Darlington Isolator

Download the MCA255 datasheet PDF. This datasheet also covers the MCA230 variant, as both devices belong to the same optically-coupled darlington isolator family and are provided as variant models within a single manufacturer datasheet.

General Description

The MCA230, MCA231 and MCA255 series of optically-coupled isolators are electrical and mechanical replacements for the Monsanto series.

Optical intercoupling provides a high degree of ac and dc isolation.

Connection to the base is also provided for design flexibility.
