Rectifier Device Data
Axial Lead Rectifier
. . . employing the Schottky Barrier principle in a large area metal–to–silicon power
diode. State–of–the–art geometry features epitaxial construction with oxide passiva-
tion and metal overlap contact. Ideally suited for use as rectifiers in low–voltage,
high–frequency inverters, free wheeling diodes, and polarity protection diodes.
