Copper, in a still air environment with T A =25°C. The value in any given application depends on the user's specific board design. B. The power dissipation PD is based on T J(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance. C. Repetitive rating, pulse width limited by junction temperature T J(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep initialTJ=25°C. D. The RθJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max. F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in 2 FR-4 board with 2oz. Copper, assuming a maximum junction temperature of T J(MAX)=150°C. The SOA curve provides a single pulse rating. Rev1 :April 2010 COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS ARE NOT AUTHORIZED.
