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 R θJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient. D. The static characteristics in Figures 1 to 6 are obtained using t ≤ 300µs pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA curve provides a single pulse rating. F. The current rating is based on the t ≤ 10s thermal resistance rating. 0 G. EAR and IAR ratings are based on low frequency and duty cycles to keep Tj=25C. Rev5: Nov. 2010 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
