Application Hints
(Continued)
As shown in the graph below, increasing the copper area
beyond 1 square inch produces very little improvement. The
minimum value for
θ
JA
for the TO-263 package mounted to a
PCB is 32C/W.
Figure 2
shows the maximum allowable power dissipation
for TO-263 packages for different ambient temperatures,
assuming
θ
is 35C/W and the maximum junction tempera-
ture is 125C.
