Copper, in a still air environment with T =25 C. The JA A value in any given application depends on the user s specific board design. B: Repetitive rating, pulse width limited by junction temperature. C. The R is the sum of the thermal impedence from junction to lead R and lead to ambient. JA JL D. The static characteristics in Figures 1 to 6 are obtained using <300 s pulses, duty cycle 0.5% max. 2 E. 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. The SOA A curve provides a single pulse rating. F. The current rating is based on the t 10s thermal resistance rating.
