藍(lan)寶(bao)寶(bao)浪(lang)(lang)涌抑制(zhi)器(qi)(qi)，英文(wen)簡稱BPSS，又(you)叫雪崩二極管，是(shi)一種利用半導體結構中載流子(zi)的(de)碰撞(zhuang)電(dian)(dian)離和渡越時間兩種物(wu)理效應(ying)而產(chan)生(sheng)負阻的(de)固體微波器(qi)(qi)件。專(zhuan)業被動保(bao)(bao)護器(qi)(qi)件供應(ying)廠商(shang)東沃電(dian)(dian)子(zi)，所(suo)供應(ying)的(de)藍(lan)寶(bao)寶(bao)浪(lang)(lang)涌抑制(zhi)器(qi)(qi)，具有(you)超(chao)強的(de)浪(lang)(lang)涌吸收(shou)能(neng)(neng)力(li)，抑制(zhi)電(dian)(dian)壓能(neng)(neng)力(li)超(chao)強，反應(ying)速度超(chao)快，通常并聯在電(dian)(dian)路(lu)中，既能(neng)(neng)解決(jue)浪(lang)(lang)涌問題，同時對靜電(dian)(dian)具有(you)超(chao)強的(de)保(bao)(bao)護效果，一個器(qi)(qi)件就能(neng)(neng)達到(dao)之(zhi)前(qian)三級(ji)防護電(dian)(dian)路(lu)的(de)效果。BPSS廣泛應(ying)用于通信電(dian)(dian)源(yuan)與基站、汽(qi)車電(dian)(dian)子(zi)、儀(yi)器(qi)(qi)儀(yi)表、工業控制(zhi)、能(neng)(neng)源(yuan)領域等。

那么(me)，您知(zhi)道(dao)藍(lan)寶寶浪涌抑制器(qi)是怎么(me)工(gong)作的嗎(ma)？它的工(gong)作原理是什么(me)呢(ni)？一起跟(gen)著東沃電子來(lai)尋找答案吧！

在材料摻雜濃(nong)度(du)較低的(de)(de)(de)(de)PN結(jie)中，當PN結(jie)反(fan)向(xiang)電(dian)(dian)(dian)(dian)壓增(zeng)加時(shi)，空(kong)(kong)間電(dian)(dian)(dian)(dian)荷區中的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)場隨著增(zeng)強。這(zhe)樣，通過空(kong)(kong)間電(dian)(dian)(dian)(dian)荷區的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)空(kong)(kong)穴(xue)(xue)(xue)，就(jiu)會在電(dian)(dian)(dian)(dian)場作(zuo)用下獲(huo)得(de)(de)的(de)(de)(de)(de)能量(liang)增(zeng) 大，在晶體中運動(dong)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)空(kong)(kong)穴(xue)(xue)(xue)將不斷地與晶體原子(zi)(zi)又發生(sheng)碰(peng)撞(zhuang)，當電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)空(kong)(kong)穴(xue)(xue)(xue)的(de)(de)(de)(de)能量(liang)足夠大時(shi)，通過這(zhe)樣的(de)(de)(de)(de)碰(peng)撞(zhuang)的(de)(de)(de)(de)可使共價(jia)鍵中的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)激發形成自(zi)由電(dian)(dian)(dian)(dian)子(zi)(zi)–空(kong)(kong)穴(xue)(xue)(xue) 對。新產(chan)生(sheng)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)子(zi)(zi)和(he)空(kong)(kong)穴(xue)(xue)(xue)也(ye)向(xiang)相反(fan)的(de)(de)(de)(de)方向(xiang)運動(dong)，重(zhong)新獲(huo)得(de)(de)能量(liang)，又可通過碰(peng)撞(zhuang)，再產(chan)生(sheng)電(dian)(dian)(dian)(dian)子(zi)(zi)–空(kong)(kong)穴(xue)(xue)(xue)對，這(zhe)就(jiu)是載流(liu)(liu)子(zi)(zi)的(de)(de)(de)(de)倍(bei)增(zeng)效應。當反(fan)向(xiang)電(dian)(dian)(dian)(dian)壓增(zeng)大到某一數值后，載 流(liu)(liu)子(zi)(zi)的(de)(de)(de)(de)倍(bei)增(zeng)情況就(jiu)像在陡峻(jun)的(de)(de)(de)(de)積雪(xue)山坡上發生(sheng)雪(xue)崩一樣，載流(liu)(liu)子(zi)(zi)增(zeng)加得(de)(de)多而快，這(zhe)樣，反(fan)向(xiang)電(dian)(dian)(dian)(dian)流(liu)(liu)劇增(zeng)， PN結(jie)就(jiu)發生(sheng)雪(xue)崩擊穿。利用該特點可制作(zuo)高反(fan)壓二極(ji)管。

藍(lan)寶寶浪涌抑制(zhi)器(qi)（雪(xue)崩二極管(guan)）是(shi)一種負(fu)阻器(qi)件(jian)，特點是(shi)輸出功率大(da)，但(dan)噪(zao)聲(sheng)(sheng)也很大(da)。主(zhu)要噪(zao)聲(sheng)(sheng)來(lai)自于(yu)雪(xue)崩噪(zao)聲(sheng)(sheng)，是(shi)由于(yu)雪(xue)崩倍增過程中產生(sheng)電子和(he)空穴和(he)無規則性所引起的(de)，其性質和(he)散彈噪(zao)聲(sheng)(sheng)類(lei)似。雪(xue)崩噪(zao)聲(sheng)(sheng)是(shi)雪(xue)崩二極管(guan)振(zhen)蕩(dang)器(qi)的(de)噪(zao)聲(sheng)(sheng)遠高于(yu)其它振(zhen)蕩(dang)器(qi)的(de)主(zhu)要原因。目前東沃電子向廣大(da)客戶供應(ying)的(de)KA系列藍寶寶浪(lang)涌抑制器(qi)，型(xing)號齊全、品(pin)質卓越、價格美麗，歡迎有需要的(de)您(nin)前來(lai)選購，免費選型(xing)，免費樣品(pin)！
