Heatsink Power Dual Black TO-220

Quick Heatsink Guide

Ohmite

This tutorial will provide an overview of heatsink operation and present a couple of examples for determining heatsink size.  This quick heatsink guide will assist in choosing a proper heatsink size based on temperature limits for popular D-PAK, TO-220, and TO-247 packages.
