THERMAL PERFORMANCE
A basic measure of a device’s thermal performance is the
junction-to-case
junction-to-foot thermal resistance, Rq
measured for the device mounted to an infinite heat sink and
is therefore a characterization of the device only, in other
words, independent of the properties of the object to which the
device is mounted.
