Abstract
Various embodiments include a fuse electrically connecting two connection regions comprising: a heat sink; a set of layers arranged on a surface of the heat sink, the set of layers including an electrically insulating layer arranged on the heat sink and an electrically conductive conductor layer arranged on a side of the insulation layer facing away from the heat sink; and an electrical connecting path between the connection regions. The surface of the heat sink defines two material cutouts. A portion of the heat sink arranged between the material cutouts forms a bridge element. The set of layers is disposed on the bridge element.
