The value of RqJAis measured with the device in a still air environment with TA =25°C. B. The power dissipation P is based on T =150°C, using junction-to-case thermal resistance, and is more useful in setting the upper D J(MAX) dissipation limit for cases where additional heatsinking is used. C. Repetitive rating, pulse width limited by junction temperature T =150°C, Ratings are based on low frequency and duty cycles to keep initial J(MAX) T =25°C. J D. The RqJAis the sum of the thermal impedance from junction to case RqJCand case to ambient. E. The static characteristics in Figures 1 to 6 are obtained using <300 m s 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 T =150°C. The SOA curve provides a single pulse rating. J(MAX) G. L=60mH, I =6.3A, V =150V, R =25Ω, Starting T=25°C AS DD G J THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
