We present a SiC Trench JFET technology that achieves a record setting specific on-resistance (RDSA) of 0.75mohm.cm2. These SiC devices are combined with optimized low voltage MOSFETs to form co-packaged cascode transistors, which provide unprecedented performance benefits, with a clear path to direct cost parity with silicon superjunction devices. These devices are shown to be useful for all circuit topologies..
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
