Abstract

High-efficiency Schottky diodes (HED) and rectifier systems having such semiconductor devices are provided, which Schottky diodes (HED) are composed of at least one Schottky diode combined with an additional semiconductor element, e.g., with magnetoresistors (TMBS) or with pn diodes (TJBS), and have trenches. Such high-efficiency Schottky diodes make it possible to construct rectifiers which are suitable for higher temperatures and can therefore be used in motor vehicle generators, without particular cooling measures such as heat sinks being required.
