晶体管

Also known as transistors

用於放大與開關電子訊號的半導體元件

AI overview

A transistor is a small electronic device that controls the flow of electric current, acting like a tiny switch or gate that can be turned on and off. Transistors are fundamental building blocks of modern electronics, enabling the operation of everything from radios and computers to smartphones and other digital devices.

晶体管（英語：transistor），早期音译为穿细丝体，是一种类似于阀门的固体半导体器件，可以用于放大、开关、稳压、信号调制和许多其他功能。在1947年，由約翰·巴丁、沃爾特·布拉頓和威廉·肖克利所發明。當時巴丁、布拉頓主要發明半導體三極體；肖克利則是發明PN二極體，他們因為半導體及電晶體效應的研究獲得1956年諾貝爾物理獎。電晶體由半導體材料組成，至少有三個對外端點稱之為極。以雙極性接面電晶體為例，有基極(B)、集極(C)、射極(E)，其中基極(B)是控制極，另外兩個端點之間的伏安特性關係是受到控制極的非線性電阻關係。電晶體受控極输入的電流或电压，改變輸出端的阻抗，從而控制通過輸出端的电流，因此晶體管可以作為電流開關，而因為晶体管輸出信號的功率可以大於輸入信號的功率，因此晶体管可以作為电子放大器。
