Patent ID: 7848104

Claim:
A power module comprising: a power device having a top electrode on its top surface and a bottom electrode on its bottom surface; an upper metal block having the lower surface connected to the top electrode; a lower metal block having the upper surface connected to the bottom electrode; a resin covering the power device, the upper metal block and the lower metal block so that the upper surface of the upper metal block and the lower surface of the lower metal block are exposed; an upper terminal-cooling power-applying block having a heat dissipation characteristic and electrical conductivity while being connected to the upper surface of the upper metal block; a lower terminal-cooling power-applying block having heat dissipation characteristic and electrical conductivity while being connected to the lower surface of the lower metal block; an upper terminal connected to the upper terminal-cooling power-applying block so as to connect the top electrode to an external component; a lower terminal connected to the lower terminal-cooling power-applying block so as to connect the bottom electrode to the external component; and an insulating case covering the power device, the upper metal block, the lower metal block, the resin, the upper terminal-cooling power-applying block, the lower terminal-cooling power-applying block, the upper terminal, and the lower terminal while being away from the upper terminal-cooling power-applying block and the lower terminal-cooling power-applying block by a predetermined distance so as to expose a part of the upper terminal and a part of the lower terminal.
