  • Publication number: 20190122966
    Abstract: A power semiconductor device is such that a notch provided, along a longitudinal end face of an inner lead, in a region of a lead frame to which the inner lead is bonded. A resistor is disposed, adjacent to the inner lead, on the same side as the notch with respect to the inner lead, and a distance between the inner lead and the notch is set to be smaller than a distance between the inner lead and the resistor, and thereby the inner lead, even when shifted in position, comes into no contact with the resistor. Because of this, it is no more necessary that a space be provided around the inner lead taking into consideration a positional shift of the inner lead, and it is possible to secure the heat release area of power semiconductor chips accordingly, and thus to obtain the small-sized and high-powered power semiconductor device.

  • Patent number: 10192811
    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.
