Component having a blocking pn junction having an edge termination structure which is formed by a further, more weakly doped region (5) and a trench (8) formed therein, said trench being filled with a dielectric. The dielectric material in the trench (8) diverts the equipotential areas from the horizontal in a very confined space in the vertical direction, with the result that the electric field can emerge from the component within a small region of the chip surface.
