A: The value of RθJA is measured with the device in a still air environment with T A =25°C. The power dissipation PDSM and current rating IDSM
are based on TJ(MAX)=150°C, using t ≤ 10s junction-to-ambient thermal resistance.
B: Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C.
C. The R θJA is the sum of the thermal impedence from junction to lead R θJL and lead to ambient.
D. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with T A=25°C. The SOA
curve provides a single pulse rating.
