The value of R θja is measured with the device mounted on in 2 FR4 board with 2oz. Copper, in a still air environment with. The value in any given application depends on the user's specific board design. B. The power dissipation P is based on T J(MAX) = C, using s junctiontoambient thermal resistance. C. Repetitive rating, pulse width limited by junction temperature T J(MAX) = C. Ratings are based on low frequency and duty cycles to keep initialt J =2 C.. The R θja is the sum of the thermal impedence from junction to lead R θjl and lead to ambient. E. The static characteristics in Figures to 6 are obtained using <µs pulses, duty cycle.% max. F. These curves are based on the junctiontoambient thermal impedence which is measured with the device mounted on in 2 FR4 board with 2oz. Copper, assuming a maximum junction temperature of T J(MAX) = C. The SOA curve provides a single pulse rating. mω COMPONENTS IN LIFE SUPPORT EVICES OR SYSTEMS ARE NOT AUTHORIZE.
