Preferred Device
Axial Lead Rectifier
This device employs the Schottky Barrier principle in a large area
metaltosilicon power diode. Stateoftheart geometry features
epitaxial construction with oxide passivation and metal overlap
contact. Ideally suited for use as rectifiers in lowvoltage,
highfrequency inverters, free wheeling diodes, and polarity
protection diodes.
