NOVELTY - The device (10) has a connection structure (2) that is located in the connection region of a doped region (3), and is contacted with doped region (3). The connection structure (2) is designed so that the diffusion is provided in the semiconductor substrate. The electrically conductive material is diffused upon the occurrence of predefined trigger conditions partially through doped region (3) up to a doped region (4). A connecting structure (5) which is arranged in connection region of the doped region (4) is coupled to the doped region (4).    USE - Device for bridging electrical energy storage device such as rechargeable battery used in mobile system such as smart phone, tablet computer, laptop, electric vehicle and hybrid vehicle.    ADVANTAGE - The reliability and operational reliability of power supply systems are increased and the costs are reduced. The contact surface between the rear panel connector of the bridging element is reduced so that the heat dissipation via the rear port is decreased. The semiconductor diode is simplified and low-current path are generated. Hence the triggering of the bridging element is performed easily and reliably.    DETAILED DESCRIPTION - The device has doped region (3) that is arranged on a surface of the semiconductor substrate. The doped region (4) is arranged adjacent to the doped region (3). The doped regions are provided with two conductivity types. The pn junction between the doped regions which is arranged on the surface of the semiconductor substrate terminal region of the doped region (3) is removed. The connection structure (2) is partially provided for diffusion in the semiconductor substrate having electrically conductive material. An INDEPENDENT CLAIM is included for a method for bridging electrical energy storage device.
