Patent ID: 8847275

Claim:
An integrated electronic component, comprising: M concentric annular semiconductor tanks, each tank having a first type of conductivity, where M is greater than or equal to two; two adjacent annular casings being separated by an annular semiconductor layer having a second type of conductivity opposite the first type of conductivity, M annular semiconductor zones, each annular semiconductor zone covering and contacting a respective one of the M annular tanks and each annular semiconductor zone including a sequence of R semiconductor regions in contact with each other, the semiconductor regions having the first and second types of conductivity alternately and being electrically coupled to each other so as to form a common annular electrode, where R is an even number greater than or equal to two, wherein each semiconductor region of one of the annular zones faces a semiconductor region of an adjacent annular zone such that two facing regions each have a different one of the first and second types of conductivity, wherein two adjacent annular casings separated by the annular layer and their two associated annular zones form R triac structures in parallel having a single common gate formed by the annular layer; a first terminal of the component being formed by at least a first annular electrode; and a second terminal of the component being formed by at least a second annular electrode.
