1. An electronic device, comprising:
a first terminal; a second terminal; a MOS transistor formed in a substrate and having a first conduction electrode coupled to the first terminal and a second conduction electrode coupled to the second terminal and including a parasitic bipolar transistor, the MOS transistor configured to, in the presence of a current pulse between the first and second terminals, operate in a hybrid mode including an operation of the MOS type in a sub-threshold mode and an operation of the parasitic bipolar transistor; a first element coupled between the first terminal and the substrate of the MOS transistor and configured for generating and injecting current into the substrate of the MOS transistor in the presence of a current pulse propagating from the first terminal to the second terminal; and a first thyristor including an anode coupled to the first terminal and a cathode coupled to the second terminal, the first thyristor triggerable at least by the first element in the presence of the current pulse propagating from the first terminal to the second terminal.
