<p>The thyristor has an SC substrate (10) of a first conduction type, forming with zones of opposite conduction type (11, 12) forming p-n junctions (16, 17) facing each other. These diffusion zones (11, 12) form the thyristor base and anode. A part (16', 17') of at least one of the junctions (16, 17) is nearer to the other junction 16, 17) than the rest of it. A control electrode (18) is opposite to the above part (16', 17') of the junction (16, 17) and forms a control zone shaped similarly to the above parts (16', 17') for the junction.</p> |
