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: Pulse width limited by max, junction temperature.
C:
The current rating is based on the t≤ 10s junction to ambient thermal resistance rating
ID=1A.
