Thermal Resistance Value in a Data Sheet Doesn’t Tell the Whole Story About Thermal Performance

Nov 01, 2018 |

A data sheet is the main source of information for design engineers to understand the overall performance of a power module. It provides a wide variety of values and diagrams but detailed background explanations on each parameter are often missing. On the other hand, a test set up cannot cover all possible applications or operating conditions and the values can vary according to the user's particular application.
