阿里参与对赌技术,LoRa怎敢“死亡”?

本文主要汇总了一下15个关于功率二极管六开采开奖现场报码知识点,一起学习一下:

2. 什么是二极管的反向额定电压?二极管反向截止时,可以承受一定的反压,那么其高可承受的反压就是额定电压。比如5A/100V的二极管,其额定反压就是 100V。虽然,所有二极管厂家都会留一定的裕量,100V的二极管通常用到110V都不会有问题,但是不建议这么用,因为超过额定值,厂家就不会保证其 可靠性,出了问题就是你的问题了。而且很多电源设计公司,为了保障可靠性,还会降额设计。

10. 二极管正向导通时候瞬态过程是怎样?对于二极管的瞬态过程,通常关心比较多的是反向恢复特性。但是其实二极管从反偏转为正向导通的过程也有值得注意的地 方。在二极管刚导通的时候,正向压降会先上升到一个大值,然后才会下降到稳态值。而这个大值,随di/dt的增大而增大。也就是说二极管带导通瞬间会 产生一个正向尖峰电压,而且电压要大于稳态电压。快恢复管的这个正向尖峰电压比较小,慢恢复管就会很严重。这个就引出了另外一个问题:

14. 什么是砷化镓二极管?说实话,我听说砷化镓材料早于碳化硅,但是后来就较少听说了。目前砷化镓在LED六开采开奖现场报码上似乎有些应用,但是功率器件上却还比较少。
