Abstract:
An electronic device comprising:two electrical terminals for connecting an electrical operating voltage with maximum values above 500 V;a silicon component connected between said two electrical terminals and being selectively in one of an on state and an off state at an operating voltage of a predetermined polarity;a semiconductor configuration made of silicon carbide with a first semiconductor region of a predetermined conductivity type and with at least one further semiconductor region of an opposite conductivity type, said first semiconductor region being more weakly doped than said at least one further semiconductor region at least in the channel region;said semiconductor configuration and said silicon component together forming an integrated hybrid component;a p-n junction formed between said first semiconductor region and said at least one further semiconductor region;said first semiconductor region having at least one channel region adjacent said p-n junction and electrically connected in series with said silicon component between said two terminals;said p-n junction being electrically connected between said two terminals in a reverse direction for the operating voltage of the predetermined polarity; anda depletion zone of said p-n junction pinching off or covering said at least one channel region of said first semiconductor region in the off state of said silicon component, said depletion zone expanding to a greater extent into said first semiconductor region.
