    • A package comprises a package body (20) with a package top side (201), a package footprint side (202) and package sidewalls (203), the package sidewalls (203) extending from the package footprint side (202) to the package top side (201); a plurality of power semiconductor chips (100) electrically connected in parallel to each other, each power semiconductor chip (100) having a first load terminal (101) and a second load terminal (102) and being configured to block a blocking voltage applied between said load terminals (101, 102) and to conduct a chip load current between said load terminals (101, 102); a lead frame structure (21) for electrically and mechanically coupling the package (200) to a carrier (300) with the package footprint side (202) facing to the carrier (300), the lead frame structure (21) comprising a plurality of first outside terminals (2111). Each first outside terminal (2111) extends out of the package body (20) for interfacing with the carrier (300). Each first load terminal (101) of the plurality of power semiconductor chips (100) is electrically connected, at least by means of one package body internal connection member (270), to at least two of the plurality of first outside terminals (2111). The package (20) further comprises a horizontally extending conduction layer (22) at the package top side (201) or at the package footprint side (202), wherein the conduction layer (22) is electrically connected with each of the second load terminals (102) of the plurality of power semiconductor chips (100).

    • A package (200) comprises: a package body (20) with an outside housing comprising at least a first package side (201), a second package side (202) and package sidewalls (203), the package sidewalls (203) extending between the first package side (201) and the second package side (202); a first electrically conductive interface layer (221) and a second electrically conductive interface layer (222) spaced apart from each other at the outside housing; a first power semiconductor chip (101) and a second power semiconductor chip (102) arranged within the package body (20), wherein both the first chip (101) and the second chip (102) exhibit a respective first load terminal (S1, S2) and a respective second load terminal (D1, D2). The first load terminals (S1, S2) are electrically connected to each other within the package body (20). The second load terminal (D1) of the first chip (101) is electrically connected to the first electrically conductive interface layer (221). The second load terminal (D2) of the second chip (102) is electrically connected to the second electrically conductive interface layer (222). The outside housing of the package body (20) further comprises a creepage structure (23) with a minimum dimension (a) between the first electrically conductive interface layer (221) and the second electrically conductive interface layer (222).
