The value of R θJA 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 Power dissipation P DSM is based on R θJA and the maximum allowed junction temperature of 150°C. The value in any given application depends on the user's specific board design, and the maximum temperature of 175 °C may be used if the PCB allows it. B. The power dissipation P D is based on T J(MAX) =175 °C, using junction-to-case thermal resistance, and is more useful in setting the upper dissipation limit for cases where additional heatsinking is used. C. Repetitive rating, pulse width limited by junction temperature T J(MAX) =175 °C. Ratings are based on low frequency and duty cycles to keep initial T J =25 °C. D. The R θJA is the sum of the thermal impedance from junction to case R θJC and case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-case thermal impedance which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T J(MAX) =175 °C. The SOA curve provides a single pulse rating. G. The maximum current rating is package limited. H. 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. Rev 1: Nov. 2011 www.aosmd.com Page 2 of 6
