To More strengthen its SiC technology, Infineon invested lots into testing on-state oxide reliability of electrically screened SiC MOSFETs as well as the off state oxide stress due to electric field conditions in SiC power devices. The earliest electrical application of SiC was being a surge protection in lightning arresters https://www.quora.com/profile/Trevor-Flatcher-2/Understanding-the-Chemical-Stability-of-Silicon-Carbide-Special-Ceramics-https-www-macrocosmmaterial-com-news-Underst
