价格很便宜的，0.7元。二极管：IN4001、IN4002～IN4007 (反向击穿电压是递增的)一般用于小工率整流IN4148一般用于小电流低电压整流IN5148大工率二极管三极管:9012、9013、9014、9015、9018、1815、1015、5551、5401、C945以上为小工率管其中9018是高频管8050、8550为中工率三极管价格比上面的三极管稍贵大工率三极管我就不说了，我接触的都是电视机的开关管和行管种类特别多，写几页也写不完，我用的都是通用的如5401、491

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，是一种电流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。晶体三极管，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。3357三极管的价格在一个2元左右，

抱歉我学不会假装 06-29 09:33

3357三极管的价格一般是2元左右。半导体三极管也称为晶体三极管，可以说它是电子电路中最重要的器件。它最主要的功能是电流放大和开关作用。三极管顾名思义具有三个电极。二极管是由一个PN结构成的，而三极管由两个PN结构成，共用的一个电极成为三极管的基极(用字母b表示)。其他的两个电极成为集电极(用字母c表示)和发射极(用字母e表示)。由于不同的组合方式，形成了一种是NPN型的三极管，另一种是PNP型的三极管。-三极管的种类很多，并且不同型号各有不同的用途。三极管大都是塑料封装或金属封装，常见三极管的外观，有一个箭头的电极是发射极，箭头朝外的是NPN型三极管，而箭头朝内的是PNP型。实际上箭头所指的方向是电流的方向。 -电子制作中常用的三极管有90××系列，包括低频小功率硅管9013(NPN)、9012(PNP)，低噪声管9014(NPN)，高频小功率管9018(NPN)等。它们的型号一般都标在塑壳上，而样子都一样，都是TO-92标准封装。在老式的电子产品中还能见到3DG6(低频小功率硅管)、3AX31(低频小功率锗管)等，它们的型号也都印在金属的外壳上
