Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A power device, comprising:
a plurality of pins; and
a package body,
the package body comprising a substrate structure, a semiconductor die, and a molded package, the semiconductor die being disposed on the substrate structure, the substrate structure comprising a heat dissipation surface connectable to a heat sink, the molded package covering the semiconductor die and the substrate structure excluding the heat dissipation surface, a through hole extending through the substrate structure and the molded package, and the molded package covering an inner wall of the through hole, the package body further comprising a top portion, a bottom portion and side portions, the top portion and the bottom portion being disposed opposite each other, a surface of the bottom portion away from the top portion being disposed facing a circuit board, the heat dissipation surface being located along the surface of the top portion, the side portions connecting the bottom portion and the top portion; and
a first end of each pin being connected to the substrate structure, a second end of each pin and the heat dissipation surface each being uncovered by the molded package, the second end of each pin comprising a mounting surface connectable to the circuit board in a surface mount manner with the pin mounting surface positioned parallel to the circuit board, the plurality of pins being distributed along the package body side portions, each pin extending from the package body side portions to the package body bottom portion, the mounting surface of each pin extending parallel along one of a bottom surface or a top surface of the circuit board, an orientation of the bottom portion being the same as that of the mounting surface of each pin.
