Abstract
In a power module that has a carrier substrate with at least one unipolar semiconductor component as a power switch, the unipolar semiconductor component is configured such that a temperature rise of the semiconductor component, from a first temperature up to which the semiconductor component heats in operation at 50% full load, to a second temperature up to which the semiconductor component heats in operation at full load, is less than a temperature rise of the semiconductor component from an initial temperature at zero load to the first temperature. As a result of the reduced temperature rise between 50% and 100% full load the service life of the power module can be lengthened.
