New #Sumitomo #SiC power transistor

New Sumitomo SiC power transistor 29 June 2015 Sumitomo Electric has developed a new silicon carbide (SiC) power transistor which achieves low on-state resistance, high stability and other excellent performance characteristics that are suited for for electric vehicles (EV)/hybrid electric vehicles (HEV), solar power conditioners and other applications. With the increasing need for energy efficiency, reducing power conversion loss is strongly required of power semiconductors. Compared with widely-utilized silicon (Si)in power devices, SiC has a higher blocking voltage and lower on-state resistance. Since these features enable dramatic reduction of the power loss of electric power apparatuses, SiC is seen as a next-generation power semiconductor. On the other hand, SiC is a compound semiconductor and its crystal defect poses a reliability-related problem. Sumitomo’s new SiC ...
