13. Application information
14. Test information
14.1 Test conditions
The junction to ambient thermal resistance, Rth(j-a) = 27.7 K/W for the HVSON8 package
when the exposed die attach paddle is soldered to 32 cm2 (5 in2) area of 35
m (1 ounce)
copper heat spreader on the demo PCB. The maximum sine wave power dissipation for
Tamb =25 °C is:
Thus, for Tamb = +85 °C the maximum total power dissipation is:
The power dissipation versus ambient temperature curve (Figure 5) shows the power
derating proles with ambient temperature for three sizes of heat spreaders. For a more
modest heat spreader using 9.7 cm2 (1.5 in2) area on the top side of the PCB, the
Rth(j-a) is 31.25 K/W. When the package is not soldered to a heat spreader, the Rth(j-a)
increases to 83.3 K/W.
