. . . employing the Schottky Barrier principle in a large metal–to–silicon power
diode. State–of–the–art geometry features epitaxial construction with oxide
passivation and metal overlay contact. Ideally suited for use in low voltage, high
frequency switching power supplies, free wheeling diodes, and polarity
protection diodes.
