SiC Power Devices
Silicon carbide (SiC) is a semiconductor material with a high electric breakdown field, saturated electron velocity, and thermal conductivity, compared to silicon (Si). Therefore, when used in semiconductor devices, they achieve higher voltage resistance, higher-speed switching, and lower ON-resistance compared to Si devices. This is expected to be a next-generation low-loss device that contribute to lower power consumption and system downsizing.
