What is Schottky diode

Schottky diode is a type of diode that utilizes Schottky barrier technology. Compared with ordinary PN junction diodes, it has the advantage of faster reverse recovery time, which is often referred to as zero reverse recovery time. Although the reverse recovery time is not really zero, it is much faster compared to ordinary diodes. Its disadvantage is that the reverse leakage current is relatively large, so it cannot be made into a high-voltage diode. At present, most Schottky diodes are below 200V. Although some companies can provide high-voltage Schottky silicon diodes, they also package several diodes in series together. Of course, some companies claim to have unique processes for manufacturing high-voltage Schottky diodes, but it is not known what kind of process it is.
