Price parity with silicon modules, greater desire in EVs, and more capacity are driving widespread adoption. The earliest electrical application of SiC was to be a surge protection in lightning arresters in electric power systems. These devices must exhibit high resistance until the voltage across them reaches a certain threshold https://www.quora.com/profile/Trevor-Flatcher-2/Silicon-carbide-special-ceramics-in-modern-industry-in-a-variety-of-applications-Silicon-Carbide-Special-Ceramics-in-Mo
