摘　　要：硅控整流器SCR作为晶闸管常用于功率器件,具有再生性和从高阻态到低阻态切换的能力。因此合理设计的SCR能成为非常高效的ESD保护电路。文章介绍了SCR的基本机制,SCR、MLSCR、LVTSCR和SCR组合保护电路的结构,并介绍了具有更好ESD性能的设计和版图。Silicon-controlled rectifiers （SCRs） also known as thyristors are devices that areused extensively in power device applications because of the capability to switch from a very high impedance state to a very low impedance state. For the samereason a properly designed SCR can also be a very efficient ESD protection circuit. The purpose of this paper is to provide an introduction to the basic mechanisms of SCR, the structure include SCR MLSCR LVTSCR and combination with SCR, and the design and layout approaches to obtain better ESD performance.
