藍(lan)(lan)寶(bao)寶(bao)TVS二(er)極管KD042，一(yi)款新型的過電(dian)(dian)(dian)壓浪(lang)涌(yong)保護器(qi)件，專(zhuan)用于保護大型貴(gui)重的電(dian)(dian)(dian)子設(she)備(bei)，如電(dian)(dian)(dian)信基礎設(she)備(bei)、鐵路軌道信號控(kong)制器(qi)、醫療機械設(she)備(bei)、工業瞬態電(dian)(dian)(dian)壓浪(lang)涌(yong)抑制系(xi)統(tong)、電(dian)(dian)(dian)網(wang)輸電(dian)(dian)(dian)系(xi)統(tong)、國防航空電(dian)(dian)(dian)子設(she)備(bei)等。與傳統(tong)的浪(lang)涌(yong)保護器(qi)相(xiang)比，藍(lan)(lan)寶(bao)寶(bao)TVS二(er)極管KD042質量(liang)更加穩定(ding)可(ke)靠(kao)、壽命更長、體(ti)積更小，且(qie)是(shi)市面上能(neng)提供最低(di)鉗(qian)位電(dian)(dian)(dian)壓的浪(lang)涌(yong)保護器(qi)件。

藍寶寶TVS二極管KD042符合UL認證和RoHS標準，且不含鉛（Pb），具體優勢特性：
√ High current transient suppressors；
√ Excellent Clamping Capability；
√ Glass Passivated chip and Bi-directional；
√ Low Slope Resistance；
√ Hazardous Substances Free；
√ High Temperature soldering: 260°C/10 seconds at terminals；
√ Epoxy Encapsulated, RoHS Compliant, UL certified；

在實際應用(yong)(yong)(yong)中，只需要一(yi)個藍寶寶浪(lang)涌(yong)保護(hu)(hu)器(qi)，就能(neng)夠代替一(yi)大串為了獲(huo)得相同(tong)的浪(lang)涌(yong)電(dian)流保護(hu)(hu)水平而并聯(lian)起(qi)來的分立TVS二極(ji)(ji)管(guan)，或者替代用(yong)(yong)(yong)SPD做(zuo)浪(lang)涌(yong)保護(hu)(hu)和大體(ti)積(ji)、笨重的防雷擊(ji)模塊。因此(ci)，可知(zhi)藍寶寶TVS二極(ji)(ji)管(guan)可節省大量電(dian)路板空間(jian)，簡(jian)化(hua)設計并減少(shao)組件數量、能(neng)夠接受(shou)無限制次數的浪(lang)涌(yong)吸收(shou)能(neng)力、標(biao)稱范圍(wei)內無損(sun)傷。同(tong)時(shi)(shi)，眾(zhong)所周知(zhi)，傳統(tong)的防雷器(qi)件模塊壽(shou)命短，使用(yong)(yong)(yong)一(yi)年左右(you)就要更(geng)換，過電(dian)壓(ya)浪(lang)涌(yong)保護(hu)(hu)選用(yong)(yong)(yong)藍寶寶TVS二極(ji)(ji)管(guan)KD042，不易老化(hua)，使用(yong)(yong)(yong)十年都不用(yong)(yong)(yong)更(geng)換，長時(shi)(shi)間(jian)工作，非常適合應用(yong)(yong)(yong)在火車控制系(xi)統(tong)中起(qi)到浪(lang)涌(yong)防護(hu)(hu)、抗干擾的重要作用(yong)(yong)(yong)。
