The Road to Success for Power Semiconductors

By Dr. Gerald Deboy, Senior Principal Power Semiconductors and System Engineering and René Mente, MSc, Staff Application Engineer, Infineon Technologies

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
