Scope
The purpose of this document is to outline the environmental conditions necessary to ensure
accuracy and repeatability for a standard junction-to-ambient (0 JA) thermal resistance
measurement in natural convection. The intent of 0jA measurements is solely for a thermal
performance comparison of one package to another in a standardized environment. This
methodology is not meant to and will not predict the performance of a package in an applicationspecific
environment.
