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. B. The Power dissipation PD is based on R θJA t ≤ 10s value and the maximum allowed junction temperature of 150°C. The value in any given application depends on the user's specific board design. C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep initial TJ =25°C. D. The RθJA is the sum of the thermal impedance from junction to case RθJC and case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300µs 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 TJ(MAX)=150°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 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
