Surface Mount
Schottky Barrier rectifiers
SCHOTTKY BARRIER
RECTIFIERS
Using the Schottky Barrier principle with a Molybdenum barrier meta. These
state-of-the-art geometry features epitaxial construction with oxide passivation
and metal overlay contact. Ideally suited for low voltage, high frequency
rectification, or as free wheeling and polarity protection diodes, in surface mount
applications where compact size and weight are critical to the system.
