Abstract

A semiconductor device includes: a first circuit including semiconductor switching elements connected in parallel, each semiconductor switching element having a first electrode, a second electrode, and a third electrode and being configured to be controlled, according to a voltage between the first electrode and the third electrode, to attain conduction or non-conduction between the second electrode and the third electrode; and a control unit connected to the first electrode of each semiconductor switching element and configured to control the voltage between the first electrode and the third electrode. The semiconductor device is configured to satisfy a first condition that an impedance Zg on a first path between the first electrodes of the respective semiconductor switching elements is higher, by at least a set value, than an impedance Zs on a third path making connection between the third electrodes of the respective semiconductor switching elements.
