Abstract: A diode, e.g., a press-fit power diode for a rectifier in a motor vehicle, includes a semiconductor chip which is connected to a head wire and a base via solder layers. A plastic sheathing, which is situated at least in the chip area and includes a plastic sleeve, enables a hard casting compound to be used and establishes a mechanical connection between the base and the head wire and forms a housing together with the base. An undercut, which extends into the casting compound, and a gap between the sleeve and the edge of the base achieve a compact design. Bevels provided on both sides enable the diode to be pressed into the rectifier from two sides.

Abstract: An electrical component, e.g., a press-in diode, is provided, which is suited for high currents and which ensures reverse-polarity protection. The electrical component includes at least one chip which is connected via soldering layers to a lead wire and a base. In the event of a rising temperature caused by polarity reversal, the clamp-type connection between the individual parts of the electrical component, e.g., the lead wire and the base, is released since the connecting plastic sheath softens, resulting in the release of the clamp-type connection, thereby interrupting the electrical connection and thus a current flow. At normal operating temperature, the clamp-type connection between the individual parts of the diode is ensured via a plastic sheath and a plastic sleeve, with bulges of the lead wire and the base protruding into the plastic sheath, thereby making the connection particularly stable.

Abstract: A diode having a press-fit base includes an axially extending mounting region for a semiconductor chip and a head wire affixed to the semiconductor chip. The head wire has a stepped wire connection or a region which forms a sealed housing together with the press-fit base and a sleeve. The cavities produced in the housing are filled with encapsulating material for stabilizing purposes, encapsulating material being present only inside the housing.
