A: The value of R JA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25C. The value in any a 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 JA is the sum of the thermal impedence from junction to lead RJL and lead to ambient. D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 s pulses, duty cycle 0.5% max. 2 E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve provides a single pulse rating.
