The value of R θja is measured with the device mounted on in FR4 board with oz. 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) =5 C, using s junctiontoambient thermal resistance. C. Repetitive rating, pulse width limited by junction temperature T J(MAX) =5 C. Ratings are based on low frequency and duty cycles to keep initialt J =5 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 <3µs pulses, duty cycle.5% max. F. These curves are based on the junctiontoambient thermal impedence which is measured with the device mounted on in FR4 board with oz. Copper, assuming a maximum junction temperature of T J(MAX) =5 C. The OA curve provides a single pulse rating. mω THI PROUCT HA BEEN EIGNE AN QUALIFIE FOR THE CONUMER MARKET. APPLICATION OR UE A CRITICAL COMPONENT IN LIFE UPPORT EVICE OR YTEM ARE NOT AUTHORIZE.
