Abstract
A transistor-clamping device for a transistor is provided with a holding block and a spring. The holding block engages over the transistor, so that the spring is pre-tensioned. A pressure plate is provided between the holding block and the transistor. The spring fixes the pressure plate on the transistor, so that a uniform pressure is applied to the transistor via the pressure plate, and, at the side facing away from the pressure plate, the latter accordingly provides a good thermal conduction to a cooling element.

A transistor-clamping device for a transistor, comprising:
- a holding block and a spring, wherein the holding block engages over the transistor, so that the spring is pre-tensioned, and further wherein:
- a pressure plate is provided between the holding block and the transistor;
- and
- the spring fixes the pressure plate on the transistor in such a manner that a uniform pressure is applied via the pressure plate to the transistor and the transistor accordingly has a direct thermal conduction to an immediately adjacent cooling element on the side facing away from the pressure plate.
