A: The value of RθJA is measured with the device in a still air environment with TA =25°C.

B. The power dissipation PD is based on TJ(MAX)=175°C, 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 TJ(MAX)=175°C.

D. The R θJA is the sum of the thermal impedence from junction to case RθJC and case to ambient.

E. The static characteristics in Figures 1 to 6 are obtained using <300

µs pulses, duty cycle 0.5% max.

F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a

maximum junction temperature of TJ(MAX)=175°C.

G. The maximum current rating is limited by bond-wires.
