Abstract
A circuit element includes an upper switching device, a lower switching device, an upper diode device, and a lower diode device. An upper drain is connected to a first terminal connected to a positive electrode of a power supply, and an upper source is connected to a third terminal. A lower drain is connected to a fourth terminal, and a lower source is connected to a second terminal connected to a negative electrode of the power supply. An upper anode is connected to the fourth terminal, and an upper cathode is connected to the first terminal. A lower anode is connected to the second terminal, and a lower cathode is connected to the third terminal. The third terminal and the fourth terminal are arranged so as to be able to be short-circuited outside of a package.
