产品概述
三极管,全称应为半导体三极管,也称双极型晶体管、晶体三极管,是一种控制电流的半导体器件。其作用是把微弱信号放大成幅度值较大的电信号,也用作无触点开关。
三极管是半导体基本元器件之一,具有电流放大作用,是电子电路的核心元件。三极管是在一块半导体基片上制作两个相距很近的PN结,两个PN结把整块半导体分成三部分,中间部分是基区,两侧部分是发射区和集电区,排列方式有PNP和NPN两种。
晶体三极管具有电流放大作用,其实质是三极管能以基极电流微小的变化量来控制集电极电流较大的变化量。这是三极管最基本的和最重要的特性。我们将ΔIc/ΔIb的比值称为晶体三极管的电流放大倍数,用符号"β"表示。电流放大倍数对于某一只三极管来说是一个定值,但随着三极管工作时基极电流的变化也会有一定的改变。
