The value of R is measured with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with T =25 C. The JA A Power Dissipation P is based on R t 10s value and the maximum allowed junction temperature of 150 C. The value in any given DSM JA application depends on the user s specific board design. B. The power dissipation PD is based on T =150 C, using junction-to-case thermal resistance, and is more useful in setting the upper 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 R is the sum of the thermal impedance from junction to case R and case to ambient. JA JC E. The static characteristics in Figures 1 to 6 are obtained using <300s 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) 2 G.These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with T =25 C. A H. L=60mH, I =4.5A, V =150V, R =25 , Starting T =25 C. AS DD G J THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
