1. A power semiconductor module device comprising:
a functional component having a plastic housing element that includes at least part of a housing for the functional component;
the function component being a substrate having conductor tracts on which power semiconductor components are arranged and contacted in an electrically conductive manner to the conductor tracts;
the plastic housing element having a plastic housing wall;
the plastic housing wall having a device identification region integrated into the plastic housing wall and being a constituent part of the plastic housing wall;
the device identification region further comprising:
a plurality of identification elements integrated into the plastic housing wall;
the identification elements are realized as a plurality of particles randomly distributed in the device identification region;
said identification elements include a portion of a surface of the plastic housing wall including the device identification elements;
the device identification region being individually specific for the device by means of the device identification elements, such that the device can be unambiguously identified by the device identification region;
at least one region of at least one of said plurality of device identification elements protrudes from the device identification region of the of the plastic housing wall surrounding them; and
wherein a determination of a coding character sequence occurs on the basis of the device identification elements having connecting vectors, the amounts and angles of which relative to one another allow the determination of identification data.
