The value of RJA is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25C. The Power dissipation PDSM is based on R JA t 10s value and the maximum allowed junction temperature of 150C. The value in any given application depends on the user's specific board design, and the maximum temperature of 150C may be u sed if the PCB allows it. B. The power dissipation PD is based on TJ(MAX)=150C, 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 TJ(MAX)=150C. Ratings are based on low frequency and duty cycles to keep initial TJ =25C. D. The RJA is the sum of the thermal impedence from junction to case RJC and case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300s pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of TJ(MAX)=150C. The SOA curve provides a single pulse ratin g. 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=25C. THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
