Original Abstract Submitted
A power module. The power module has a substrate and at least one power transistor situated on a lower side of the substrate, and at least one temperature sensor situated in the power module. At least one primary temperature sensor is situated on an upper side opposite the at least one power transistor or in an inner substrate layer situated above the at least one power transistor. At least one reference temperature sensor for providing a comparison temperature is situated at a distance from all power transistors, on the upper side or on one of the inner substrate layers. As a result, the transistor temperature can be measured closer to the source of the heat and a reference temperature is provided for detecting resistance changes due to material aging.
