A molded semiconductor package includes: a semiconductor die embedded in a mold compound; a first heat spreader partly embedded in the mold compound and thermally coupled to a first side of the semiconductor die; and a second heat spreader partly embedded in the mold compound and thermally coupled to a second side of the semiconductor die opposite the first side. The first heat spreader includes at least one heat dissipative structure protruding from a side of the first heat spreader uncovered by the mold compound and facing away from the semiconductor die. The mold compound is configured to channel a fluid over the at least one heat dissipative structure in a direction parallel to the first side of the power semiconductor die. Corresponding methods of production and electronic assemblies are also described.
