CMLD4448DO

CMLD4448DOG

SURFACE MOUNT

DUAL, ISOLATED, OPPOSING

HIGH SPEED SILICON

SWITCHING DIODES

DESCRIPTION:

The CENTRAL SEMICONDUCTOR CMLD4448DO

and CMLD4448DOG each contain two (2) Isolated

Opposing Configuration, Silicon Switching Diodes,

manufactured by the epitaxial planar process, epoxy

molded in a PICOmini™ surface mount package.

These devices are designed for high speed

switching applications.
