A: The value of RθJA is measured with the device mounted on 1in² FR-4 board with 2oz. Copper, in a still air

environment with TA=25°C. The value in any given application depends on the user's specific board design.

B: Repetitive rating, pulse width limited by junction temperature.

C: The

current rating is based on the t≤ 10s junction to ambient thermal resistance rating.
