Figure 1: Comparison of Superjunction transistor, SiC MOSFET, and GaN HEMT

The commercial availability of Superjunction transistors 20 years ago, challenged and finally proved wrong the limitations of conventional silicon-based transistors with respect to on-state resistance. What was regarded as revolutionary at that time is standard today. Today there is not a single transistor from 25
