WESTCODE UKN282CH20 N0606YS20可控硅二极管 

由于压敏电阻的通流容量大，残压低，抑制过电压能力强；平时漏电流小，放电后不会有续流，元件的标称电压等级多，便于用户选择；伏安特性是对称的，可用于交、直流或正负浪涌；因此用途较广。
2、 过电流保护
由于半导体器件体积小、热容量小，特别像晶闸管这类高电压大电流的功率器件，结温必须受到严格的控制，否则将遭至彻底损坏。当晶闸管中流过大于额定值的电流时，热量来不及散发，使得结温迅速升高，将导致结层被烧坏。
产生过电流的原因是多种多样的，例如，变流装置本身晶闸管损坏，触发电路发生故障，控制系统发生故障等，以及交流电源电压过高、过低或缺相，负载过载或短路，相邻设备故障影响等。
晶闸管过电流保护方法常用的是快速熔断器。由于普通熔断器的熔断特性动作太慢，在熔断器尚未熔断之前晶闸管已被烧坏；所以不能用来保护晶闸管。快速熔断器由银制熔丝埋于石英沙内，熔断时间较短，可以用来保护晶闸管。快速熔断器的性能主要有以下几项表征。
