Notes:

1.Rθ JA 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. Rθ JC is guaranteed by design while Rθ CA is determined by the user's board design.

a) 350°C/W when mounted on a minimum pad..

Scale 1 : 1 on letter size paper

2. Pulse Test: Pulse Width ≤ 300 ∝ s, Duty Cycle ≤ 2.0%
