Abstract:
A thyristor is disclosed with a plurality of emitter shorts at points in the cathode region. The points define a Delaunay triangulation with a plurality of triangles. For a first subset of triangles a coefficient of variation of the values qT,l with l∈S1 is smaller than 0.1, and/or an absolute value of a skewedness of the geometric quantities qT,l with l∈S1 is smaller than 5, and/or a Kurtosis of the geometric quantities qT,l with l∈S1 is smaller than 20. For a second subset of triangles, a quotient of a standard deviation of the quantities qT,m with m∈S2 and a mean squared value of the geometric quantity qT,l with l∈S1 is less than 1, and/or a quotient of a number of triangles in the second subset and a number of triangles in the first subset is less than 1.0×10−2.
