m ΩForward Transconductance A. The value of R θJA is measured with the device mounted on 1in 2
FR-4 board with 2oz. Copper, in a still air environment with T A =25°C. The value in any given application depends on the user's specific board design.B. The power dissipation P D is based on T J(MAX)=150°C, using ≤ 10s junction-to-ambient thermal resistance.
C. Repetitive rating, pulse width limited by junction temperature T J(MAX)=150°
C. Ratings are based on low frequency and duty cycles to keep initialT J =25°C.
D. 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 1 to 6 are obtained using <300µs pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-ambient thermal impedence which is measured with the device mounted on 1in 2 FR-4 board with
2oz. Copper, assuming a maximum junction temperature of T J(MAX)=150°
C. The SOA curve provides a single pulse ratin g.
