A: The value of RθJA is measured with the device in a still air environment with T A =25°C. The power dissipation P DSM and current rating IDSM
are based on TJ(MAX)=150°C, using steady state junction-to-ambient ther mal resistance.
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 RθJA 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. The SOA curve provides a single pulse ratin g.
G. These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
H. The maximum current rating is limited by bond-wires.
*This device is guaranteed green after data code 8X11 (Sep 1ST 2008).
