Notes:
1. RqJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RqJC is guaranteed by
design while RqCA is determined by the user's board design.

Typical RqJA for single device operation using the board layouts shown below on 4.5"x5" FR-4 PCB in a still air environment:
a. 78oC/W when mounted on a 0.5 in2 pad of 2oz cpper.
b. 125oC/W when mounted on a 0.02 in2 pad of 2oz cpper.
c. 135oC/W when mounted on a 0.003 in2 pad of 2oz cpper.
