Surface Mount
Schottky Power Rectifier
. . . employing the Schottky Barrier principle in a large area metal–to–silicon
power diode. 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.
