to-220ab是特定的jedec编号，“ab”是指符合特定的测量规范的3个直插脚编号。 TO-220-3 是通用的编号，指具有TO-220本体和3引脚的物料。 如今，相同的封装系列中还会有2脚、3脚、5脚或7脚等选择。

Sometimes the designation is followed by the number of leads, as in TO-220AB-5L for five leads, etc. There also some vendor-specific variations such as International Rectifier 's SUPER-220, which dispenses with the hole in favor of clip-mounting, thus claiming TO-247-like thermal performance in a TO-220 footprint.

在读Datasheet时，我们可能会对MOSFET Package的编码感到奇怪。如下图，你会发现“器件封装”编码为TO-220AB，而“封装/外壳”的编码则为TO-220-3。 TO-220AB. TO-220AB是特定的 JEDEC 编码，“AB”是指符合特定的测量规范的3个直插脚编。

本文详细介绍了to-220封装编号不同后缀——如to-220ab与to-220-3——概念的定义与区别，帮助工程师正确选型。 关键词: to-220ab, to-220-3, 器件, 封装, 区别在查看封装时，人们可能会对物料封装的编号感到困惑。

2015年12月8日 · to-220ac与to-220ab这两种当初海矽美设计就是为了电路不同功能而设计的，单管的to-220ac电路中主要是为了实现电路当中单相导通的功能，而to-220ab封装多数用于开关电源当中，充放电时转换之用，以及结合电路作续流之用，相信有这方面工程师对此也都很熟悉了。
