Copper, in a still air environment with TA =25°C. The value in any given application depends on the user's specific board design. B. The power dissipation PD is based on TJ(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance. C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C. Ratings are based on low frequency and duty cycles to keep initial TJ =25°C. D. The RθJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max. #REF! F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in2 FR-4 board with 2oz. Copper, assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse ratin g.
