Abstract
A semiconductor switching device includes a package, and a semiconductor switching element provided in the package and having a collector electrode and an emitter electrode. A main collector terminal and a main emitter terminal reflect voltage drop generated during application of current by a floating component in the package. A second collector terminal and a second emitter terminal detect a voltage between the collector electrode and the emitter electrode without reflecting the voltage drop. A third emitter terminal is arranged close to the second emitter terminal, and detects the voltage drop generated between the main emitter terminal and the second emitter terminal.
