DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMSH3-20L and
CMSH3-40L 4.0 Amp surface mount low VF silicon
Schottky rectifiers are highly reliable components
designed for use in all types of commercial, industrial,
entertainment, computer, and automotive applications
where high efficiency is required. To order devices on
16mm Tape and Reel (3000/13” Reel), add TR13 suffix
to part number.
