1. An electric component assembly, comprising a semiconductor component and a carrier, said carrier containing a thermally conductive ceramic and being connected to at least one varistor body, wherein heat from the semiconductor component can be at least partially dissipated to the carrier of the varistor body, wherein the varistor body contains a composite material composed at least of a varistor ceramic as matrix and a thermally conductive material as filler, wherein the thermally conductive material differs from the varistor ceramic, wherein the filler is present as a homogenous distribution of highly thermally conductive particles in the varistor body, and wherein the filler is highly thermally conductive ceramics selected from the group consisting of hafnium oxide and manganese oxide.
