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