Abstract:
1. A power semiconductor module comprising: a power semiconductor element; a case for receiving the power semiconductor element; a control terminal which is connected to a control electrode of the power semiconductor element, the control terminal has a portion that is protruding from an upper surface of the case; and a conductive spring arranged around the control terminal so that an inner surface of the spring makes contact with at least a part of the side surface of the control terminal, the conductive spring is electrically connected to a printed substrate in a compressed state, the printed substrate placed opposed to the upper surface of the case by making pressurization contact with the compressed conductive spring, and in an uncompressed state, (i) a length of the conductive spring is greater than a length of the protruding portion of the control terminal, and (ii) an upper portion of the conductive spring is not arranged around the control terminal in the uncompressed state.
