TIP41 Transistor package

• The transistor package used for TIP41 is to-220
• The main specialty of the TO-220 package is its temperature resistance capability.
• The to-220 body is divided into two portions, the first portion is made with plastic and epoxy material, and the second portion is made with a metal tab.
• The metal tab acts as a heat sink and a to-220 package had a hole for attaching it with heat sink or with PCB.
