Copper, in a still air environment with T A =5 C. The Power dissipation P SM is based on R θja and the maximum allowed junction temperature of 15 C. The value in any given application depends on the user's specific board design, and the maximum temperature of 175 C may be used if the PCB allows it. B. The power dissipation P is based on T J(MAX) =175 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) =175 C.. 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 1 to 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) =175 C. G. The maximum current rating is limited by bondwires. H. These tests are performed with the device mounted on 1 in FR4 board with oz. Copper, in a still air environment with T A =5 C. The SOA curve provides a single pulse rating. *This device is guaranteed green after data code X11 (Sep 1 ST ). Rev 7 : May THIS PROUCT HAS BEEN ESIGNE AN QUALIFIE FOR THE CONSUMER MARKET.
