  • Patent number: 11848354
    Abstract: A power semiconductor device includes a semiconductor body coupled to first and second load terminals. The body includes: at least a diode structure configured to conduct a load current between the terminals and including an anode port electrically connected to the first load terminal and a cathode port electrically connected to the second load terminal; and drift and field stop regions of the same conductivity type. The cathode port includes first port sections and second port sections with dopants of the opposite conductivity type. A transition between each of the second port sections and the field stop region forms a respective pn-junction that extends along a first lateral direction. A lateral separation distance between immediately adjacent ones of second port sections in a second group is smaller than in a first group.
