ABSTRACT:
A semiconductor power module capable of efficiently utilizing the performance of the module and facilitating management of the module in custody. The semiconductor power module having one or more semiconductor power switching elements and a drive unit is provided with a non-volatile memory for storing use history of the module and a drive unit. The use history contains information of one of the number of switching times of the semiconductor power switching element, the number of over-current detections of the semiconductor power switching element and a temperature rise of the semiconductor power module.
