Note 1:

Theta-JA (



JA) is the thermal resistance from junction to ambient when the package is mounted on an 8-layer JEDEC standard test

board and dissipating maximum power.

Note 2:

Theta-JP (



JP) is the thermal resistance from junction to the center exposed pad on the bottom of the package.

Note 3:

For all numbers in the table, the exposed pad is connected to the ground plane with a 9x9 array of thermal vias; via diameter

0.33mm; via pitch 0.76mm.
