Abstract [en]

This paper reviews the current state of the art in active switching device performance for SiC BJTs. In addition, some results from simulations are shown with particular attention on temperature and design dependence of the current gain. A design to improve conductivity modulation is also suggested. Finally, performance of a 2.8 kV BJT are illustrated. This device demonstrates high current gain of 52, low on-resistance of 6.8 mΩcm 2, fast switching, and no bipolar degradation.
