Full Plastic Dual Schottky Barrier Power Rectifiers
SCHOTTKY BARRIER
RECTIFIERS
Using the Schottky Barrier principle with a Molybdenum barrier metal.
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.
