我们从事电路设计、仪器研制时,常常用到半导体二极管和晶体三极管以及光电器件.同时,在科研、生产、教学工作中,为了有效地利用国外某些已有的成果或对国内外电子电路进行选择、分析和鉴定时,还会遇到若干国家的不同产品.为了能迅速地对电路工作状态进行定性分析及优缺点对比,往往需要掌握各国半导体器件的命名方法。本文将系就介招我国产品;苏、美、日、英、西德、法国及西欧联合体系的命名方法。文末提供 We are engaged in circuit design, equipment development, often use semiconductor diodes and transistors and optoelectronic devices.At the same time, in scientific research, production, teaching work, in order to effectively use some of the existing foreign achievements or domestic and foreign electronic circuits Selection, analysis and identification, but also encounter a number of different countries in the product. In order to quickly work on the circuit state qualitative analysis and the advantages and disadvantages of contrast, often need to master the naming of semiconductor devices in various countries. This article will introduce Department of China's products; the Soviet Union, the United States, Japan, Britain, West Germany, France and Western Europe, the naming system.
