Abstract
A single chip power diode includes a semiconductor body having an anode region coupled to a first load terminal and a cathode region coupled to a second load terminal. An edge termination region surrounding an active region is terminated by a chip edge. The semiconductor body thickness is defined by a distance between at least one first interface area formed between the first load terminal and the anode region and a second interface area formed between the second load terminal and the cathode region. At least one inactive subregion is included in the active region. Each inactive subregion: has a blocking area with a minimal lateral extension of at least 20% of a drift region thickness; configured to prevent crossing of the load current between the first load terminal and the semiconductor body through the blocking area; and at least partially not arranged adjacent to the edge termination region.
