肖特基整流二极管介绍一、引言肖特基势垒二极管（Schottky barrier diode简称SBD）是一种金属（或金属硅化物）/ 半导体接触的器件，它是多子器件，主要用其非线性电阻的特性。
SBD是最古老的半导体器件，1904年开始，矿石检波器就得到了应用。
SBD在超高频及微波电路中用于检波和混频，都是用其正向非线性电阻的特性。
SBD长期用金属与半导体接触进行制作，稳定性差，是可靠性最差的半导体器件之一。
八十年代开始对金属硅化物深入研究，用金属硅化物代替金属，获得了可靠而又重复的肖特基势垒，为大规模生产奠定了基础。
各种家用电器、微电脑、汽车电子、通讯设备、仪器、国防军工都要求电子设备轻量化、小型化，特别是要求采用小型化和高效率的电源。
高频开关电源随着工作频率的提高，其体积和重量都会明显减小，同时效率显著提高，高频开关电源越来越受到人们的重视。
SBD 有三大特点：（1）速度快（多子器件，无少子储存效应）；(2)正向压降低；（3）散热性能好。
SBD与通常的PN结整流器件相比，SBD具有开关速度快（高频）、导通电压低（高效）、抗电流浪涌冲击能力强（大电流）。
低输出电压（V0≤±24V）的高频开关电源多采用肖特基整流二极管。
世界高频开关电源年销售额约为500亿美圆，这是一个巨大的市场!对肖特基整流二极管的规模生产有巨大的拉动力。
SBD制作简单、工艺流程短、成本低、有利于大规模生产。
肖特基整流二极管在高频开关电源电路中起开关作用，是用其正、反向非线性电阻的特性（不再只是用正向非线性电阻的特性）。
肖特基整流二极管的名称较多，有功率肖特基二极管、肖特基续流二极管、大电流肖特基二极管、肖特基开关二极管等等。
肖特基势垒与p-n结的比较肖特基二极管的势垒可以比做在同一种半导体上的p-n结低许多，例如硅，p-n结的内建势V bi≥0.8V；而肖特基结势垒电势为0.5V～0.6V很容易做到。
在同一电流密度下，p-n结上的正向压降比肖特基二极管上的电压降至少高0.3V。
