Package Thermal Characteristics
The device junction to case thermal characteristic is
θjc, and the junction to ambient air characteristic is
θja. The thermal characteristics for θja are shown with two different air flow rates.
Maximum junction temperature is 150
°C.
A sample calculation of the absolute maximum power dissipation allowed for a CPGA 175-pin package at
commercial temperature and still air is as follows:
