Overview

This class introduces the concepts of junction temperature and thermal resistance, and then explains how to use the thermal parameters to compare alternative candidate devices, to estimate the junction temperature, and to build compact thermal models.

Learning Objectives

Given a set of thermal parameters from the datasheet, learn how to:

select among alternative candidate devices for better cooling performance;
estimate the junction temperature;
select thermal parameters for building compact thermal models.

Definition and usage of common thermal parameters.
