Overview
The 1N5819G Schottky Rectifier, produced by onsemi, is a high-performance Schottky barrier diode designed for use in low-voltage, high-frequency applications. This diode employs the Schottky Barrier principle in a large area metal-to-silicon power diode, featuring chrome barrier metal, epitaxial construction with oxide passivation, and metal overlap contact. It is ideally suited for use as rectifiers in low-voltage, high-frequency inverters, free-wheeling diodes, and polarity protection diodes.
