  • SYSTEM AND METHOD FOR DETERMINING SINGLE EVENT BREAKDOWN VOLTAGE FOR WIDE BANDGAP SEMICONDUCTOR POWER DEVICE
    Publication number: 20250351472
    Abstract: A system and method for determining a single event breakdown voltage for a wide bandgap semiconductor power device. The power device includes an epitaxial layer composed of a wide bandgap semiconductor material such as SiC having a critical energy density. A specific doping level is applied to the epitaxial layer based on a relationship between doping level and the critical energy density to produce a power device with a specific single event breakdown voltage.
