Patent ID: 8890313

Claim:
An electronic device, comprising: a first chip and a second chip of semiconductor material each of which includes electronic components, each chip including a first conduction terminal on a first surface of the chip and a second conduction terminal on a second surface of the chip opposite the first surface of the chip; and an insulating body encapsulating the first chip and the second chip; and a first heat-sink electrically coupled with the first conduction terminal of said first chip and with the first conduction terminal of said second chip; a second heat-sink electrically coupled with the second conduction terminal of said first chip and with the second conduction terminal of said second chip, at least one of the first heat-sink and the second heat-sink including a portion exposed from the insulating body; and a first conductive lead and a second conductive lead configured to extend from the insulating body and configured to mount the electronic device with a through-hole mount on an electronic board, the first conductive lead being electrically coupled with the first heat-sink and the second conductive lead being electrically coupled with the second heat-sink, the first conductive lead and the second conductive lead having a first exposed surface and a second exposed surface, respectively, that are exposed from the insulating body, the first exposed surface being greater than the second exposed surface.
