SEMICONDUCTOR TECHNICAL DATA
The SWITCHMODE Power Rectifier employs 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 use as rectifiers in very low–voltage, high–frequency switching power
supplies, free wheeling diodes and polarity protection diodes.
