三极管8050是非常常见的NPN型晶体三极管，在各种放大电路中经常看到它，应用范围很广，主要用于高频放大。也可用作开关电路。本文主要来了解一下s8050三极管和ss8050三极管区别。

三极管管脚识别方法：

（a）判定基极。用万用表欧姆档100或欧姆档1k挡测量管子三个电极中每两个极之间的正、反向电阻值。当用第一根表笔接某一电极，而第二表笔先后接触另外两个电极均测得低阻值时，则第一根表笔所接的那个电极即为基极b。这时，要注意万用表表笔的极性，如果红表笔接的是基极b。黑表笔分别接在其他两极时，测得的阻值都较小，则可判定被测管子为PNP型三极管；如果黑表笔接的是基极b，红表笔分别接触其他两极时，测得的阻值较大，则被测三极管为NPN型管如8050，9014，9018。

（b）判定三极管集电极c和发射极e。（以PNP型三极管为例）将万用表置于欧姆档100或欧姆档1K挡，红表笔集电极c，用黑表笔分别接触另外两个管脚时，所测得的两个电阻值会是一个大一些，一个小一些。在阻值小的一次测量中，黑表笔所接管脚为基极；在阻值较大的一次测量中，黑表笔所接管脚为发射极。

S8050是一款小功率NPN型硅管，集电极-基极（Vcbo）电压最大可为40V，集电极电流为（Ic）0.5A。S8050是电路硬件设计最常用半导体三极管型号之一。

s8050三极管和ss8050三极管的区别：

●S8050功耗（Pcm）：0.625W（Tamb=25℃）

●集电极电流（Icm）：0.5A SS8050

●功耗（Pcm）：1W（Tamb=25℃）

●集电极电流（Icm）：1.5A

行内常称SS为原装进口，S为国产的。
