Abstract
An overvoltage protection device, including: an input configured to be connected to a power supply mains; an output configured to be connected to an electronic system to be protected; two bidirectional field-effect semiconductor transistors of normally-on type, connected in series between the input and the output, fabricated in a wide-bandgap material and configured to operate in current-limiting mode; and a resistor connected in parallel with the two transistors.
