1. A packaged power electronic device, comprising:
a first support element having a first face and a second face, the first face of the first support element including a first thermal dissipation surface of the device;
a second support element having a first face and a second face, the first face of the second support element including a second thermal dissipation surface of the device, the first and the second support elements overlapping each other with the respective second faces facing each other;
a first power component attached to the second face of the second support element;
a second power component attached to the second face of the first support element;
a third power component attached to the second face of the second support element and side by side with the first power component;
a first contacting element overlapping the second power component;
a second contacting element overlapping the first power component;
a third contacting element overlapping the third power component, and the third contacting element arranged side by side with the second contacting element and electrically insulated from the second contacting element;
a first lead electrically coupled with the first power component through the second support element;
a second lead electrically coupled with the second power component through the first support element; and
a thermally conductive body arranged between the first and second contacting elements,
wherein the first and second support elements and the first and second contacting elements include electrically insulating and thermally conductive multilayers.
