Abstract: When a power semiconductor device is energized, heat generated from upper-side power semiconductor chips mounted on a P-potential electrode transfers to a first heat mass portion and a second heat mass portion, and heat generated from lower-side power semiconductor chips mounted on a intermediate potential electrode transfers to a resistor. A lead frame, the power semiconductor chip, an inner lead and the resistor are placed in symmetry with respect to a centerline, which can reduce the difference among the temperature increases of the power semiconductor chips when energized. In this way, transient temperature increase of the power semiconductor chip can be suppressed without adding a new member, such as a heat diffusion plate.
