Abstract
The invention concerns a semiconductor power element (diode ) having a lead ( ) and a safety fuse ( ) situated in the main current path that blows when overheated, particularly for use in the electrical system of motor vehicles. In order to achieve a previously determined, purposeful disconnection of the endangered element in order to avoid consequential damages when semiconductor power elements become overloaded, it is proposed that a segment ( ) of the lead ( ) and/or its points of contact in the main current path of the semiconductor be designed as a safety fuse ( ) that blows when a specified, current-dependent temperature value is reached.
