Abstract
A single chip power semiconductor device includes: first and second load terminals; a semiconductor body integrated in the single chip and coupled to the load terminals and configured to conduct a load current along a load current path between the load terminals; a control terminal and at least one control electrode electrically connected thereto, the at least one control electrode being electrically insulated from the semiconductor body and configured to control the load current based on a control voltage between the control terminal and the first load terminal; a protection structure integrated, separately from the load current path, in the single chip and including a series connection of pn junctions with first semiconductor regions of a first conductivity type and second semiconductor regions of a second conductivity type. The series connection of the pn-junctions is connected in forward bias between the control terminal and the first load terminal.
