CMSH3-20L

CMSH3-40L

SURFACE MOUNT SILICON

LOW VF

SCHOTTKY RECTIFIERS

4.0 AMP, 20 AND 40 VOLT

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

FEATURES:

• 4.0 Amp average forward current

(upgraded from 3.0 Amps)

• Low forward voltage drop

• High current capability

• High reliability

• Flammability classification UL94V-0

• “C” bend construction provides strain relief when

mounted on a PC board

* Upgraded Specification

MAXIMUM RATINGS: (TA=25°C unless otherwise noted)
