Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient resistance where the case thermal reference is defined as the solder mounting surface of the drain
pins. RθJC is guaranteed by design while RθCA is determined by the user's board design.
a. 78°C/W when mounted on a 1in2 pad of 2oz copper on FR-4 board.
b. 156°C/W when mounted on a minimum pad.
2. Pulse Test: Pulse Width ≤ 300 µs, Duty Cycle ≤ 2.0%
