  • Publication number: 20230123783
    Abstract: A semiconductor module includes a semiconductor die, an encapsulation encapsulating the die, and first and second power contacts electrically coupled to the die. The power contacts each include an external part exposed from the encapsulation and an overlapping part. The power contacts are configured to carry respective first and second currents. A current flow of the first current in the external part of the first power contact points into or out of the semiconductor module. A current flow of the second current in the external part of the second power contact points in the opposite direction of the first current flow. The overlapping parts overlap such that the current flows point in the same direction in the overlapping parts. The overlapping parts include overlapping slots configured to accept a current sensor element for measuring a combined current in the overlapping parts.
