The value of R θJA is measured with the device in a still air environment with T A =25°C. B. The power dissipation PD is based on TJ(MAX)=150°C, using junction-to-case 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 TJ(MAX)=150°C, Ratings are based on low frequency and duty cycles to keep initial TJ =25°C. D. The R θJA is the sum of the thermal impedance from junction to case R θJC and case 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-case thermal impedance which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse rating. G.
