The value of R qja is measured with the device mounted on in 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 qja t s and the maximum allowed junction temperature of 5 C. The value in any given application depends on the user's specific board design. B. The power dissipation P D is based on T J(MAX) =5 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. Single pulse width limited by junction temperature T J(MAX) =5 C. D. The R qja is the sum of the thermal impedance from junction to case R qjc and case to ambient. E. The static characteristics in Figures to 6 are obtained using <3 ms pulses, duty cycle.5% max. F. These curves are based on the junction-to-case thermal impedance which is measured with the device mounted to a large heatsin k, assuming a maximum junction temperature of T J(MAX) =5 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 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A =25 C. I.
