Claims

[Scope of utility model registration request]

A transistor chip directly fixed onto a metal base with the collector side facing down, a flywheel diode chip connected between the collector and emitter of this transistor chip, and an emitter connected to the emitter of the transistor chip. In the transistor module, the diode chip is directly fixed with its cathode side down in a position different from the transistor chip on the metal base, and an emitter drawer is provided on the opposite anode side of the transistor module. A transistor module characterized in that a conductor is mounted and directly fixed.
