Title:
パワー半導体装置およびそれを用いた電力変換装置
Document Type and Number:
Japanese Patent JP6771447
Kind Code:
B2
Abstract:
An object is to suppress a decrease in reliability due to peeling of an insulating layer and another member of a power semiconductor device. A power semiconductor device according to the present invention includes: a power semiconductor element; a conductor portion that transmits a current to the power semiconductor element; an insulating layer in contact with a surface of the conductor portion on a side opposite to a side on which the power semiconductor element is arranged; a metallic heat dissipating portion that opposes the conductor portion while sandwiching the insulating layer; and an output terminal that is connected to the conductor layer and outputs a different signal depending on a contact state of the insulating portion, the insulating layer having an insulating portion and a conductor layer sandwiched between the conductor portion and the metallic heat dissipating portion via the insulating portion.
