Package Thermal Specifications
Thermal parameters are measured or estimated for devices with the exposed pad soldered to thermal
vias in a multilayer 2S2P PCB per JESD51. Thermal resistance is measured from the die to the
ambient air. The values provided are based on the package body, die size, maximum power
consumption, 85°C ambient temperature, and 125°C junction temperature of the die.
Use the following formulas to calculate the junction temperature:
