Using the schottky barrier principle with a molybdenum barrier metal. These state-of-the-art geometry features epitaxial construction with oxide passivation and metal overlay contact. Ideally suited for low voltage, high frequency rectification, or as free wheeling and polarity protection diodes. Features: Low forward voltage. Low switching noise. High current capacity. Guarantee reverse avalanche. Guard-ring for stress protection. Low power loss and high efficiency. 125C operating junction temperature. Low stored charge majority carrier conduction.
