SURFACE MOUNT SILICON
SCHOTTKY RECTIFIERS
1.0 AMP, 20 THRU 100 VOLT
DESCRIPTION:
The CENTRAL SEMICONDUCTOR CMMSH1 Series
are high current Schottky rectifiers in the SOD-123F
surface mount package. These devices are suitable for
design applications such as AC/DC, DC/DC converters,
and reverse battery protection circuits in a variety of
portable and battery powered products.
