AI overview

A diode is an electronic component made from semiconductor material that allows electric current to flow in one direction while blocking it in the other. Diodes are used in many applications, such as converting alternating current to direct current in power supplies and protecting circuits from damage caused by reversed current flow.

ダイオード（英: diode）は整流作用（電流を一定方向にしか流さない作用）を持つ電子素子である。最初のダイオードは2極真空管で、後に半導体素子である半導体ダイオードが開発された。その後も研究が進み、今日では非常に様々な種類のダイオードが存在する。
