...A type of semiconductor device. From the perspective of an external circuit, it has two stable states equivalent to a switch, and can switch from the off state to the on state or vice versa. It has three or more p-n junctions and is mainly used to control the flow of power by its switching action. In other words, it is used as a power conversion device or a semiconductor switch. Its capacity ranges widely from a few hundred volts and a few amperes used in home appliances to several thousand volts and several thousand amperes for power systems. ... *Some terminology explanations that mention "native breed" are listed below.

…半導体デバイスの一種。外部回路から見ると,スイッチと等価のような二つの安定状態をもち,オフ状態からオン状態へ,あるいはまたその逆の切替えを行える。三つ以上のp‐n接合をもち,そのスイッチング作用により電力の流れを制御する目的におもに使用される。すなわち,電力変換装置や半導体のスイッチとしての応用である。その容量は家電製品で用いられる数百V,数A級のものから,電力システム用の数千V,数千A級まで広範囲にわたっている。… ※「native breed」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
