Barrier rectifiers. SKM34 Datasheet
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
