Abstract
An electronic device includes: a control terminal, which extends on a first face of a substrate; a first conduction terminal, which extends in the substrate at the first face of the substrate; a first insulating layer interposed between the control terminal and the first conduction terminal; a conductive path, which can be biased at a biasing voltage; and a protection element, coupled to the control terminal and to the conductive path, which forms an electrical connection between the control terminal and the conductive path and is designed to melt, and thus interrupt electrical connection, in the presence of a leakage current higher than a critical threshold between the control terminal and the first conduction terminal through the first insulating layer.
