產(chǎn)品概述
三極管,全稱應(yīng)為半導(dǎo)體三極管,也稱雙極型晶體管、晶體三極管,是一種控制電流的半導(dǎo)體器件。其作用是把微弱信號(hào)放大成幅度值較大的電信號(hào),也用作無(wú)觸點(diǎn)開(kāi)關(guān)。
三極管是半導(dǎo)體基本元器件之一,具有電流放大作用,是電子電路的核心元件。三極管是在一塊半導(dǎo)體基片上制作兩個(gè)相距很近的PN結(jié),兩個(gè)PN結(jié)把整塊半導(dǎo)體分成三部分,中間部分是基區(qū),兩側(cè)部分是發(fā)射區(qū)和集電區(qū),排列方式有PNP和NPN兩種。
晶體三極管具有電流放大作用,其實(shí)質(zhì)是三極管能以基極電流微小的變化量來(lái)控制集電極電流較大的變化量。這是三極管最基本的和最重要的特性。我們將ΔIc/ΔIb的比值稱為晶體三極管的電流放大倍數(shù),用符號(hào)"β"表示。電流放大倍數(shù)對(duì)于某一只三極管來(lái)說(shuō)是一個(gè)定值,但隨著三極管工作時(shí)基極電流的變化也會(huì)有一定的改變。
