下载“第Ⅲ章:晶体管” (PDF:2.0MB)
双极晶体管有两种类型:NPN型和PNP型。NPN型产品涵盖低耐受电压到高耐受电压产品。耐受电压为400V或以下的PNP型产品,特别是耐受电压为200V或以下的PNP型产品是主流产品。
它们有放大功能,可以将小信号转换成大信号。集电极电流IC与基极电流IB(IC/IB)之比称为直流电流增益,用hFE表示。
当小电流(IB)从基极流向发射极时,IB×hFE的电流IC从集电极流向发射极。
BJT是由基极电流驱动的电流驱动器件。
NPN晶体管的操作
基极电流:从基极到发射极的电流
集电极电流:从集电极到发射极的电流
PNP晶体管的操作
基极电流:从发射极到基极的电流
集电极电流:从发射极到集电极的电流
