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

Are you SiC of Silicon? â€

Anup Bhalla, Vice President Engineering, UnitedSiC

Ultra-High Voltage SiC and Supercascodes New applications are emerging that require high voltage switch technology which is significantly lower in balance-of-system costs and operating losses than silicon IGBT and IGCT technology. This spans a wide range from solid state transformers, MW motor drives,
