is the internal resistance from the junction to the back of the die. A heat sink customized to the end user application and
ambient operating environment is required to ensure the die junction temperature is maintained within the limits defined in Table 3-2 on
page 15. For more information about thermal management, see Section 5.7 on page 61.
