三极管是电子电路中最常见的器件之一。在各种电子电路中的应用十分广泛。但是，判定三极管的好坏及极性是初学者碰到的一个难点。
　　多给自己一点信心，看完以下内容后。你就可以自信的说：我也能把三极管的B，C，E揪出来了。　　首先我们要理解一个常识上的问题，数字万用表处于二极管档时，红表笔代表正电极。
　　开始动手，选数字万用表的二极管挡，用红表笔去接三极管的某一管脚<假设作为基极>，用黑笔分别接另外两个管脚，如果表的液晶屏上两次都显示有零点几伏的电压<锗管为0.3左右。硅管为0.7左右>。那么此管应为NPN管且红表笔所接的那一个管脚是基极。如果两次所显的为‘OL’那么红表笔所接的的那一个管脚便是PNP型管的基极。
　　在判别出管子的型号和基极的基础上，可以再判别发射极和集电极。仍用二极管挡，对于NPN管令红表笔接其‘B’极，黑表笔分别接另两个脚上，两次测得的极间电压中，电压微高的那一极为‘E’极，电压低一些的那极为‘C’极。如果是PNP管，令黑表笔接其‘B’极，同样所得电压高的为‘E’极电压低一些的为‘C’。---例如：用红表笔接C9018的中间那个脚<B极>，黑表笔分别接另外两个管脚，可得0.719伏，0.731伏两个电压值。其中0.719伏为“B”与“C”之间的电压，0.731伏为“B”与“E”之间的电压。
　　判别三极管的好坏，只要查一下三极管各PN结是否损坏，通过万用表测量其发射极，集电极的正向电压和反向电压来判定。如果测得的正向电压与反向电压相似且几乎为零。或正向电压为‘OL’说明三极管已经短路或断路。
　　现在感觉如何!与用电阻法量测三极管相比较，哪一种更爽？
　　附：<1>经试验已测得：A1078<PNP>,C3332<NPN>,C9545<NPN>,N222A<NPN>,A733<PNP>,3904<NPN>,3
906<PNP>,90**系列<如：9011<NPN>，9012<PNP>，9013<NPN>，9014<NPN>，9015<PNP>，9016<NPN>，9018<NPN>>等晶体管适用于上述测量的方式。
　　<2>所试验的三极管都为TO---92封装。试验的环境----在5度至35度的条件下试验都正确。
　　<3>文中的“OL”是指万用表不能正常显示数字时而出现的一固定符号，出现什么样的固定符号‘要看是使用什么牌子的万用表而定’。如：有的万用表则会显示一固定符号”l”。
　　<4>A1078<PNP>,C3332<NPN>,C9545<NPN>,N222A<NPN>,A733<PNP>,这五种三极管的中间那个管脚为“C”极。
　　3904,3906,和90**系列的三极管，中间那个管脚为“B”极。
