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

SiC MOSFET Efficiency and Protection without Compromise

Click image to enlarge

Figure 1. Comparing SiC with conventional Silicon MOSFETs reveals the clearly superior semiconductor characteristics of the SiC material, which allows the construction of significantly smaller switching devices

The lower sheet resistance of wide-bandgap SiC materials (typically 1/100th that of conventional silicon) results in smaller devices for a given current capacity – valuable in space saving applications. In addition, the electric-breakdown- field for SiC (approximately 2.8 MV/cm) allows for a much
