Understanding Silicon Carbide Schottky Diode Performance

Silicon SiC Schottky rectifiers are gaining increasing traction in high-power applications due to their superior operation compared to traditional silicon-based alternatives. A key factor influencing their effectiveness is the lowering of reverse leakage. Elevated temperatures, a common phenomenon in power electronics, exacerbate this issue, demanding careful evaluation of device layout. The Schottky barrier height, dependent on the work function of the metal and the SiC surface condition, is a critical value to control for optimal behavior. Furthermore, series resistance, arising from the substrate material and interfaces, can degrade yield and generate undesirable heat. Therefore, a complete understanding of these impacts is essential for robust power network design and successful integration.
