【技术】探讨贴片二极管不同分类
合科泰半导体在本文将对如何区分贴片二极管进行详细的讲解,为工程师们的设计提供理论基础。详细介绍内容如下:
什么是贴片二极管?
贴片二极管的英文是(Diode)。贴片二极管是用P型半导体和N型半导体做成的,在P型半导体和N型半导体相结合的地方,就会形成一个特殊的薄层,这个特殊的薄层就叫“PN结”。半导体贴片二极管实际上就是由一个PN结构成的 ,半导体是一种特殊物质,它不像导体那样能够完全导电,也不像绝缘体那样不能导电,它是介于导体与半导体之间,所以称为半导体贴片二极管。贴片二极管具有单向导电性,符号是一个三角形旁边划一竖线。三角形表示正极竖线表示负极。
贴片二极管的分类
一、按半导体材料分类:
1.锗[ zhě ]贴片二极管 化学元素代号(Ge)
2.硅[ guī ]贴片二极管 化学元素代号(Si)
二、根据其封装分类:
根据封装形式分为塑料封装(塑封)贴片二极管、玻璃封装(玻封)贴片二极管、金属封装贴片二极管、片状贴片二极管等
三、根据电流容量分类:
根据电流容量分为大功率贴片二极管(5A以上)、中功率贴片二极管(1~5A)和小功率贴片二极管(1A以下);
大功率类:R-6封装(10A05,10A1,10A2,10A4,104A,10A8,10A10)10A
中功率类:DO-214AD(IN5820 , IN5821 , IN5822) 电流3A
小功率类:DO-35(IN4148 )150mA
四、根据其用途分类:
1.检波贴片二极管
2.整流贴片二极管
3.稳压贴片二极管
4.开关贴片二极管
5.贴片肖特基二极管
6.变容贴片二极管
7. 瞬变电压抑制贴片二极管(TVS管)
8.发光贴片二极管(LED)
