Copper, in a still air environment with T = C. The Power dissipation SM is based on R θj and the maximum allowed junction temperature of C. The value in any given application depends on the user's specific board design, and the maximum temperature of 75 C may be used if the PCB allows it. B. The power dissipation is based on T J(MX) =75 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 T J(MX) =75 C. D. The R θj is the sum of the thermal impedence from junction to case R θjc and case to ambient. E. The static characteristics in Figures to 6 are obtained using < µs pulses, duty cycle.5% max. F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a maximum junction temperature of T J(MX) =75 C. G. The maximum current rating is limited by bond-wires. H. These tests are performed with the device mounted on in 2 FR-4 board with 2oz. Copper, in a still air environment with T = C. The SO curve provides a single pulse rating. THIS PRODUCT HS BEEN DESIGNED ND QULIFIED FOR THE CONSUMER MRKET.
