Claims

[Scope of utility model registration request]

In a power transistor module configured as a large current switching device by connecting a plurality of transistors in parallel, the difference in path length of each emitter current between each emitter terminal of each transistor and a common emitter terminal is calculated. A power transistor module comprising a connecting conductor that is made as small as possible to measure current balance between the transistors.
