The value of R θja is measured with the device mounted on in FR board with oz. Copper, in a still air environment with T A = C. The Power dissipation P M is based on R θja and the maximum allowed junction temperature of C. The value in any given application depends on the user's specific board design, and the maximum temperature of 7 C may be used if the PCB allows it. B. The power dissipation P is based on T J(MAX) =7 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) =7 C. Ratings are based on low frequency and duty cycles to keep initial T J = 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 to 6 are obtained using <3µs pulses, duty cycle.% 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) =7 C. The OA curve provides a single pulse rating.. The maximum current limited by package. H. These tests are performed with the device mounted on in FR board with oz.
