可控硅又称晶闸管(Silicon Controlled Rectifier, SCR)。
自从20世纪50年代问世以来已经发展成了一个大的家族，它的主要成员有单向晶闸管、双向晶闸管、光控晶闸管、逆导晶闸管、可关断晶  可控硅闸管、快速晶闸管，等等。 　　
可控硅整流器件是一种非常重要的功率器件，可用来做高电压和高电流的控制。
可控硅器件主要用在开关方面，使器件从关闭或是阻断的状态转换为开启或是导通的状态，反之亦然。
可控硅器件与双极型晶体管有密切的关系，二者的传导过程皆牵涉到电子和空穴，但可控硅的开关机制和双极晶体管是不同的，且因为器件结构不同，可控硅器件有较宽广范围的电流、电压控制能力。
现今的可控硅器件的额定电流可以从几毫安到5000A以上，额定电压可以超过10000V。
下面将讨论基本可控硅器件的工作原理，然后给出一些高功率和高频率的可控硅器件。
