Understanding how heat flows out of a power module is crucial for power design. This webinar explains how thermal resistance is derived by a power module manufacturer, some techniques used for measurement, and how the values given in a datasheet can vary between module types and manufacturers. ​​​​​​​ Additionally, the concept of thermal coupling and how operating modes influence thermal resistance will be discussed. This webinar is a natural extension to the previous webinar “How to Read an IGBT Datasheet.”
