In an external lead terminal 5 of a transistor module, an intermediate terminal portion 6 and an external lead terminal 8 are conductively connected to each other via a U-shaped intermediate terminal portion 7 having a curved portion 7b. Connected in parallel with this intermediate terminal portion 7 is a shortcircuit wire 9 having a larger electric resistance and a smaller inductance than the same. For this reason, even if a current is reduced suddenly in a state in which the current is flowing from the external terminal portion 8 to the intermediate terminal portion 6 via the intermediate terminal portion 7, the current shifts to the shortcircuit wire 9 side, so that a transient voltage is low. Consequently, it is provided a transistor module capable of reducing a transient voltage without being subjected to restrictions in the size of an external lead terminal while maintaining a high level of reliability. |
