A: The value of R θ JA is measured with the device mounted on 1in 2 FR-4 board with 2oz. Copper, in a still air environment with T A =25 ° C. The
value in any given application depends on the user's specific board design. The current rating is based on the t ≤ 10s thermal resistance rating.
B: Repetitive rating, pulse width limited by junction temperature.
C. The R θ JA is the sum of the thermal impedence from junction to lead R θ JL and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using <300 μ s pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A =25 ° C. The SOA
curve provides a single pulse rating.
