Abstract:
1. A voltage-controlled monolithic component of triac type, formed in a substrate of a first conductivity type, including: first and second vertical thyristors, a first main electrode of the first thyristor, on a front surface side of the component, corresponding to a first region of a first conductivity type formed in a first well of a second conductivity type, said first well corresponding to a first main electrode of the second thyristor, the first well containing a second region of the first conductivity type; and a pilot structure including, on the front surface side, above an extension of a second main electrode region of the second thyristor, a second well of the second conductivity type containing third and fourth regions of the first conductivity type, the third region and a portion of the second well being connected to a gate terminal, the fourth region being connected to the second region.
