Wayon維安代理肖特基二極管Schottky DIODE

Wayon維安代理肖特基二極管Schottky DIODE

肖特基二極管是貴金屬(金、銀、鋁、鉑等)A為正極,以N型半導(dǎo)體B為負(fù)極,利用二者接觸面上形成的勢壘具有整流特性而制成的金屬-半導(dǎo)體器件
產(chǎn)品概述
肖特基二極管肖特基(Schottky)二極管,又稱肖特基勢壘二極管(簡稱 SBD),它屬一種低功耗、超高速半導(dǎo)體器件。最顯著的特點(diǎn)為反向恢復(fù)時(shí)間極短(可以小到幾納秒),正向?qū)▔航祪H0.4V左右。其多用作高頻、低壓、大電流整流二極管、續(xù)流二極管、保護(hù)二極管,也有用在微波通信等電路中作整流二極管、小信號檢波二極管使用。在通信電源、變頻器等中比較常見。
一個(gè)典型的應(yīng)用,是在雙極型晶體管 BJT 的開關(guān)電路里面,通過在 BJT 上連接 Shockley 二極管來箝位,使得晶體管在導(dǎo)通狀態(tài)時(shí)其實(shí)處于很接近截止?fàn)顟B(tài),從而提高晶體管的開關(guān)速度。這種方法是 74LS,74ALS,74AS 等典型數(shù)字 IC 的 TTL內(nèi)部電路中使用的技術(shù)。
肖特基(Schottky)二極管的最大特點(diǎn)是正向壓降 VF 比較小。在同樣電流的情況下,它的正向壓降要小許多。另外它的恢復(fù)時(shí)間短。它也有一些缺點(diǎn):耐壓比較低,漏電流稍大些。選用時(shí)要全面考慮。
