All Semiconductor Switch Technologies Lead to Rome

Figure 1: Si superjunction and SiC MOSFETs have a vertical structure; GaN MOSFETs on the other hand have a lateral structure

Much is made of wide bandgap technologies, especially since GaN and SiC often have a superior performance on paper when compared to classic Si switching devices. These improvements include lower on-resistance and higher thermal conductivity, features that enable improvements in efficiency and operation at higher te
