A. The value of R θ JA is measured with the device in a still air environment with T A =25°C.
B. The power dissipation P D is based on T J(MAX) =175°C in a TO252 package, using junction-to-case thermal resistance, and is more useful in setting
the upper dissipation limit for cases where additional heatsinking is used.
C. Repetitive rating, pulse width limited by junction temperature T J(MAX) =175°C.
D. The R θ JA is the sum of the thermal impedance from junction to case R θ JC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 μ s pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal imped ance which is measured with the device mounted to a large heatsink, assuming a
maximum junction temperature of T J(MAX) =175°C.
G.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.
H. L=60mH, I AS =3.4A, V DD =150V, R G =10 ? , Starting T J =25°C
