thermal resistance of the package (junction to case + case to ambient) and is mainly specified as a reference parameter. (This is when a heat sink is
not present and the top surface of the package is essentially acting as the heat sink). However, in devices that have high power dissipation, heat sink
usage is highly desirable. Consequently, system designers may have limited use for this parameter.
