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 Power dissipation PDSM is based on R θJA and the maximum allowed junction temperature of 150°C. The value in any given
application depends on the user's specific board design, and the maximum temperature of 175°C may be used if the PCB allows it.
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 T J(MAX)=175°C.
D. The R θJA is the sum of the thermal impedence from junction to case R θJC 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.
H. 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.
*This device is guaranteed green after data code 8X11 (Sep 1 ST 2008).
