传统的半导体三极管(又称晶体三极管或晶体管)由两个PN结和三个电极构成,从结构上看有NPN和PNP两种基本类型.其工作原理是大家所熟知的.晶体管的成功研制极大的带动了半导体工业的发展.晶体管的应用已渗入到国民经济的各个领域.但半导体晶体管也存 The traditional semiconductor transistor (also known as transistor or transistor) consists of two PN junction and three electrodes, from the structural point of view there are two basic types of NPN and PNP. The working principle is well known. The successful development of the transistor pole Big led the development of the semiconductor industry. Transistor applications have penetrated into all areas of the national economy, but also the semiconductor transistors
