TVS管是(shi)采用(yong)半(ban)導體(ti)工藝制(zhi)成的(de)(de)單個PN結或多個PN結集(ji)成的(de)(de)器(qi)件(jian)，是(shi)一種新型高效過(guo)(guo)(guo)(guo)電(dian)壓(ya)防浪(lang)涌(yong)保(bao)護器(qi)件(jian)，被廣(guang)泛應(ying)用(yong)于(yu)(yu)敏感電(dian)子零件(jian)過(guo)(guo)(guo)(guo)壓(ya)保(bao)護中。當(dang)電(dian)路(lu)(lu)出現異常(chang)過(guo)(guo)(guo)(guo)電(dian)壓(ya)并達到(dao)TVS擊穿電(dian)壓(ya)時(shi)(shi)，TVS迅速由高電(dian)阻(zu)(zu)狀(zhuang)態(tai)(tai)轉變為低(di)電(dian)阻(zu)(zu)狀(zhuang)態(tai)(tai)，泄放由異常(chang)過(guo)(guo)(guo)(guo)電(dian)壓(ya)導致的(de)(de)瞬時(shi)(shi)過(guo)(guo)(guo)(guo)電(dian)流到(dao)地，同時(shi)(shi)把異常(chang)過(guo)(guo)(guo)(guo)電(dian)壓(ya)鉗制(zhi)在較低(di)的(de)(de)水平，從而保(bao)護后(hou)級電(dian)路(lu)(lu)免(mian)遭異常(chang)過(guo)(guo)(guo)(guo)電(dian)壓(ya)的(de)(de)損(sun)壞(huai)。當(dang)異常(chang)過(guo)(guo)(guo)(guo)電(dian)壓(ya)消失后(hou)，TVS阻(zu)(zu)值(zhi)又恢復到(dao)了高阻(zu)(zu)態(tai)(tai)。電(dian)路(lu)(lu)正常(chang)工作時(shi)(shi)，TVS處于(yu)(yu)高阻(zu)(zu)狀(zhuang)態(tai)(tai)，不(bu)影響(xiang)電(dian)路(lu)(lu)正常(chang)工作。

TVS管種類繁多，有貼片（SOD-123、SMA/DO-214AC、SMB/DO-214AA、SMC/DO-214AB、DO-218AB）直(zhi)插（DO-41、DO-15、DO-201、R-6/P600、NA）之分，功率200W-30000W，工(gong)作電壓3.3V-600V，型號(hao)齊全(quan)。

穩(wen)壓(ya)(ya)管(guan)也叫齊(qi)納二(er)極管(guan)，是一種用(yong)特(te)殊工藝制造成的(de)(de)面結型硅(gui)半導(dao)體二(er)極管(guan)。在被(bei)反向(xiang)擊穿后，盡管(guan)流(liu)過(guo)穩(wen)壓(ya)(ya)管(guan)的(de)(de)反向(xiang)擊穿電(dian)(dian)流(liu)變化很大(da)，但兩端的(de)(de)電(dian)(dian)壓(ya)(ya)卻幾乎不變。在實際應用(yong)中，常(chang)(chang)常(chang)(chang)用(yong)它這一特(te)性來進行穩(wen)壓(ya)(ya)，以(yi)獲得基準電(dian)(dian)壓(ya)(ya)和用(yong)作電(dian)(dian)平(ping)轉移(yi)，被(bei)廣(guang)泛應用(yong)于穩(wen)壓(ya)(ya)電(dian)(dian)源、電(dian)(dian)子點火器(qi)、直流(liu)電(dian)(dian)平(ping)平(ping)移(yi)、限(xian)幅電(dian)(dian)路、過(guo)壓(ya)(ya)保護電(dian)(dian)路、補償電(dian)(dian)路等當中。

穩壓管(guan)種(zhong)類繁多(duo)，有(you)貼(tie)片(pian)（SMA/DO-214AC、SOD-123、SMB/DO-214AA、SMC/DO-214AB）直(zhi)插（DO-41、DO-15、DO-201）之分，額定(ding)功耗1W、1.5W、2W、3W、5W，穩壓值(zhi)3.3V-330V，型號齊全(quan)。

由此可知，TVS管和穩壓管是兩種功能和作用完全不同的二極管，不能相互替代！想了解更多有關TVS管和穩壓管選型、應用、型號、價格等方面信息，可直接咨詢東沃電子：136 7581 6901（微信同號）朱經理
