Understanding Silicon Carbide Schottky Diode Characteristics

Silicon carbide Schottky diodes are gaining growing traction in high-power fields due to their superior operation compared to traditional silicon-based counterparts. A key element influencing their effectiveness is the lowering of reverse leakage. Elevated temperatures, a common phenomenon in power electronics, exacerbate this challenge, demanding careful consideration of device layout. The Schottky contact height, dependent on the work function of the metal and the SiC surface condition, is a critical value to control for optimal response. Furthermore, effective resistance, originating from the material material and connections, can degrade yield and generate undesirable heat. Therefore, a complete understanding of these effects is vital for dependable power network design and successful integration.
