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 5 C. The value in any given application depends on the user's specific board design, and the maximum temperature of 75 C may be used if the PCB allows it. B. The power dissipation P D is based on T J(MAX) =75 C, using junctiontocase 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) =75 C. D. The R θja is the sum of the thermal impedence from junction to case R θjc and case to ambient. E. The static characteristics in Figures to 6 are obtained using <3 µs pulses, duty cycle.5% max. F. These curves are based on the junctiontocase thermal impedence which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T J(MAX) =75 C. G. The maximum current rating is limited by bondwires. H. These tests are performed with the device mounted on in 2 FR4 board with 2oz. Copper, in a still air environment with T A =25 C. The SOA curve provides a single pulse rating. *This device is guaranteed green after data code 8X (Sep ST 28). Rev9: Feb 2 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
