階躍二極管


  階躍二極管又被稱為階躍恢復(fù)二極管,從導(dǎo)通切換到關(guān)閉時(shí)的反向恢復(fù)時(shí)間trr短,因此,其特長是急速地變成關(guān)閉的轉(zhuǎn)移時(shí)間顯著地短。如果對階躍二極管施加正弦波,那么,因tt(轉(zhuǎn)移時(shí)間)短,所以輸出波形急驟地被夾斷,故能產(chǎn)生很多高頻諧波。它也是一種具有PN結(jié)的二極管。


  階躍二極管是一種特殊的變?nèi)莨?,也稱作電荷儲(chǔ)存二極管,簡稱階躍管,它具有高度非線性的電抗,應(yīng)用于倍頻器時(shí)代獨(dú)有的特點(diǎn),利用其反向恢復(fù)電流的快速突變中所包含的豐富諧波,可獲得高效率的高次倍頻,它是微波領(lǐng)域中優(yōu)良的倍頻元件。


  國創(chuàng)階躍二極管型號(hào)如下:


WY0002H階躍二極管WY46階躍二極管
WY373A階躍二極管WY373B階躍二極管
WY373C階躍二極管WY402A階躍二極管
WY402B階躍二極管WY402C階躍二極管
WY402D階躍二極管WY411A階躍二極管
WY411B階躍二極管WY411C階躍二極管



  階躍恢復(fù)二極管的特性:在存儲(chǔ)電荷消失之后(t=ts時(shí))反向電流突然降為0,即消除了關(guān)斷時(shí)的反向電流拖尾。這種二極管不僅具有極短的下降時(shí)間,而且也具有很好的正向?qū)щ娦阅?。目前階躍管主要用于倍頻電路和超高速脈沖整形和發(fā)生電路中! 更多關(guān)于雪崩二極管型號(hào)及其他的詳細(xì)信息可以來電咨詢國創(chuàng)電子,如需采購,可直接撥打我們的熱線電話:029-85251919,專業(yè)工程師免費(fèi)為您答疑解惑。
