Theta-JA (θJA) is the junction-to-ambient thermal resistance, when the package is mounted on a four-layer JEDEC
standard test board with no airflow and dissipating maximum power.
Neither performance nor reliability is guaranteed outside these limits. Extended operation outside these limits might adversely
affect device reliability.
