Understanding Silicon Carbide Schottky Diode Characteristics
Silicon carbide Schottky rectifiers are gaining significant traction in high-power applications due to their superior operation compared to traditional silicon-based alternatives. A key element influencing their effectiveness is the minimization of reverse current. Elevated temperatures, a common occurrence in power electronics, exacerbate this issue, demanding careful evaluation of device design. The Schottky junction height, based on the work function of the contact and the SiC surface condition, is a critical value to control for optimal behavior. Furthermore, effective resistance, stemming from the material material and interfaces, can degrade efficiency and generate unwanted heat. Therefore, a complete understanding of these influences is crucial for reliable power network design and successful integration.
