Abstract
Abstract At least four electrodes are provided on the same surface of a discrete transistor. Among these electrodes, one electrode is set as a base electrode, an electrode neighboring the base electrode in the up-and-down direction is set as an emitter electrode and an electrode neighboring the base electrode in the right-and-left direction is set as a collector electrode. On the same surface, a base electrode is provided at a position which is neither in the up-and-down direction nor in the right-and-left direction with respect to the base electrode. When the discrete transistor having this type of electrode arrangement is mounted on a substrate, one of the base electrodes formed on the substrate is connected to a first wiring, the collector electrode is connected to a second wiring, and the emitter electrode is connected to a third wiring.
