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.
MARKING CODES: CMSH3-20L: CS320L
CMSH3-40L: CS340L
• High reliability
• Flammability classification UL94V-0
• “C” bend construction provides strain relief when
mounted on a PC board
MAXIMUM RATINGS: (TA=25°C unless otherwise noted)
