Abstract:
The electronic device includes a first (BP) and a second (BN) terminal and electronic means coupled between said two terminals; the electronic means include at least one block (BLC) comprising an MOS transistor (TR) including a parasitic bipolar transistor, the MOS transistor having the drain (D) thereof coupled to the first terminal (BP), the source (S) thereof coupled to the second terminal (BN) and being additionally configured, in the event of a current pulse (IMP) between the two terminals, to operate in a hybrid mode including MOS operation in a subthreshold mode and operation of the parasitic bipolar transistor. The device can comprise two blocks (BLC1, BLC2) connected symmetrically between the two terminals (BP, BN) with a triac (TRC) the trigger of which is connected to the common terminal (BC) of the two blocks.
