Understanding Silicon Carbide Schottky Diode Characteristics

Silicon SiC Schottky diodes are gaining growing traction in high-power applications due to their superior operation compared to traditional silicon-based alternatives. A key aspect influencing their effectiveness is the reduction of reverse flow. Elevated temperatures, a common occurrence in power electronics, exacerbate this challenge, demanding careful assessment of device architecture. The Schottky junction height, reliant on the work function of the electrode and the SiC surface condition, is a critical characteristic to control for optimal function. Furthermore, series resistance, stemming from the substrate material and connections, can degrade effectiveness and generate excessive heat. Therefore, a thorough understanding of these effects is crucial for reliable power system design and productive integration.
