The invention relates to a power electronic switching device having a substrate, which has a non-conductive insulation layer on which at least one first conductor track 40 and at least one second conductor track 50 are applied. The first conductor track 40 is assigned an electrical DC voltage potential DC+ of the power electronic switching device and the one second conductor track 50 is assigned an electrical AC voltage potential AC of the power electronic switching device. At three first partial power switches are arranged on the first conductor track. At least three second partial power switches are arranged on the second conductor track. The at least three first partial power switches are connected electrically in parallel with each other to form a first parallel circuit and the at least three second partial power switches are electrically connected in parallel with each other to form a second parallel circuit. The at least three first partial power switches and the at least three second partial power switches are arranged on the substrate 30 in a chessboard-like pattern.
