The value of R θja is measured with the device mounted on in FR4 board with oz. Copper, in a still air environment with T A = C. The Power dissipation P DSM is based on R θja t s value and the maximum allowed junction temperature of 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) = C, using junctiontocase 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) = 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 to are obtained using <3µs pulses, duty cycle.% max. F. These curves are based on the junctiontocase thermal impedance which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T J(MAX) = 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 FR4 board with oz. Copper, in a still air environment with T A = C. mω THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
