壓(ya)敏電(dian)(dian)(dian)(dian)阻(zu)是一種電(dian)(dian)(dian)(dian)壓(ya)敏感型器件(jian)，其工作(zuo)原理基于(yu)非(fei)線性特性。在正常電(dian)(dian)(dian)(dian)壓(ya)下（低于(yu)額(e)定電(dian)(dian)(dian)(dian)壓(ya)或稱(cheng)為(wei)“闕口”電(dian)(dian)(dian)(dian)壓(ya)），它(ta)的(de)(de)阻(zu)值極高(gao)、接近無窮大(da)；而(er)當電(dian)(dian)(dian)(dian)路中出(chu)現過(guo)(guo)電(dian)(dian)(dian)(dian)壓(ya)時(shi)——比如瞬態高(gao)電(dian)(dian)(dian)(dian)壓(ya)或者浪涌(yong)電(dian)(dian)(dian)(dian)流等(deng)(deng)(deng)異常情況——它(ta)的(de)(de)內阻(zu)會(hui)急劇(ju)下降并迅速導(dao)通(tong)大(da)量電(dian)(dian)(dian)(dian)流，同時(shi)將過(guo)(guo)高(gao)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)箝位在一個(ge)相對(dui)固定的(de)(de)數值上(shang)，保護(hu)后級(ji)電(dian)(dian)(dian)(dian)路的(de)(de)安全(quan)穩定運行。這種快速響應(ying)的(de)(de)特性使得(de)它(ta)在納秒級(ji)別的(de)(de)時(shi)間內就能對(dui)過(guo)(guo)壓(ya)的(de)(de)沖擊(ji)(ji)做出(chu)反應(ying)，從而(er)有效(xiao)防(fang)止(zhi)因雷擊(ji)(ji)、電(dian)(dian)(dian)(dian)網波動(dong)等(deng)(deng)(deng)原因引起(qi)的(de)(de)設(she)備(bei)(bei)損壞問題發生(sheng)；并且由于(yu)具有良好的(de)(de)耐(nai)高(gao)壓(ya)與(yu)大(da)電(dian)(dian)(dian)(dian)流的(de)(de)能力(li)以及(ji)較長的(de)(de)使用(yong)壽命和(he)高(gao)穩定性等(deng)(deng)(deng)特點而(er)被廣(guang)泛應(ying)用(yong)于(yu)各種電(dian)(dian)(dian)(dian)子設(she)備(bei)(bei)中作(zuo)為(wei)重要的(de)(de)防(fang)護(hu)元件(jian)之一：例如電(dian)(dian)(dian)(dian)源(yuan)線路保護(hu)和(he)通(tong)訊設(she)備(bei)(bei)的(de)(de)防(fang)雷擊(ji)(ji)等(deng)(deng)(deng)方面都少(shao)不了它(ta)的(de)(de)存在和(he)幫(bang)助作(zuo)用(yong)呢(ni)！此外根據制(zhi)作(zuo)材料不同還可以分為(wei)氧化鋅類和(he)非(fei)氧化鋅類等(deng)(deng)(deng)類型來滿足不同的(de)(de)應(ying)用(yong)需求哦~
