  • Publication number: 20230411254
    Abstract: A molded power semiconductor package includes power semiconductor dies embedded in a mold compound and a lead frame embedded in the mold compound above the power semiconductor dies. A first part of the lead frame includes branches electrically connected to a first load terminal of the power semiconductor dies. A second part of the lead frame is spaced inward from the branches of the first part, and electrically connected to a gate terminal of the power semiconductor dies. The first part of the lead frame has a protrusion that juts out from a first side face of the mold compound to form a first lead of the molded package. A longitudinal axis of the second part of the lead frame intersects the first lead. The second part of the lead frame is physically disconnected from the first lead by a severed region of the lead frame.
