NMOS的实物图和引脚分布如下图所示。什么是肖特基二极管肖特基二极管又叫势垒二极管，是由金属和半导体接触形成的二极管，其特点为：反向恢复时间非常短，为ns级别；正向导通压降非常低：为0.3-0.5V左右；漏电流较大、反向击穿电压比较低；通常用在低压开关电源中，以肖特基二极管MBR30100为例，其实物图和结构图如下图所示。该肖特基二极管有三个电极，其中一个公共端是阴极，由两个二极管共阴极构成。关于场效应管的反向并接的二极管的问题?有些场效应管的规格书里原理图上标有一个稳压管符号，为了搞清楚其中的真正情况，我们抽取了几种有该二极管符号的样品进行检测试验，发现有以下两种情况：1.实际是本体的寄生二极管；2集成的肖特基二极管前一种情况，估计是做文件时直接将其他文件中的图形复制过来所致。
