Abstract

A power semiconductor device includes a portion and an external package enclosing the portion. The portion includes a ceramic board sides provided on the ceramic board defining a space filled with a thermal insulator, and a silicon carbide power semiconductor element enclosed within the thermal insulator. The external package is made of a material having a thermal conductivity lower than that of the side.
