A short-circuit semiconductor component comprises a semiconductor body, in which a rear-side base region of a first conduction type, an inner region of a second complementary conduction type, and a front-side base region of the first conduction type are disposed. The rear-side base region is electrically connected to a rear-side electrode, and the front-side base region is electrically connected to a front-side electrode. A turn-on structure, which is an emitter structure of the second conduction type, is embedded into the front-side base region and/or rear-side base region and is covered by the respective electrode and is electrically contacted with the electrode placed on the base region respectively embedding it. It can be turned on by a trigger structure which can be activated by an electrical turn-on signal. In the activated state, the trigger structure injects an electrical current surge into the semiconductor body, which irreversibly destroys a semiconductor junction.

Short-circuit semiconductor component and method for operating it

A short-circuit semiconductor component comprises a semiconductor body, in which a rear-side base region of a first conduction type, an inner region of a second conduction type complementary to the first conduction type, and a front-side base region of the first conduction type are disposed. The rear-side base region is electrically connected to a rear-side electrode with a rear-side electrode width, and the front-side base region is electrically connected to a front-side electrode with a front-side electrode width. A turn-on structure with a turn-on structure width is embedded into the front-side and/or rear-side base region and is covered by the respective electrode. The turn-on structure is configured to be turned on depending on a supplied turn-on signal and to produce, on a one-off basis, an irreversible, low-resistance connection between the two electrodes. The ratio of the turn-on structure width to the respective electrode width is less than 1.

A disk cell for pressure contacting a plurality of semiconductor components via a clamping device to generate a clamping force. The disk cell includes a housing comprising at least one metallic pressure plate, a first semiconductor component arranged in the housing, and a second semiconductor component arranged in the housing. The first and second semiconductor components are different. The at least one metallic pressure plate reaches across and clamps the first and second semiconductor components, is substantially perpendicular to the clamping force, and is arranged so that the clamping force acts on the at least one metallic pressure plate to provide a local region of influence to clamp the first and second semiconductor components. The first semiconductor component is arranged below the local region of influence of the clamping force. The second semiconductor component is at least partially arranged outside the local region of influence of the clamping force.
