( 150 ? 85 ) = 36 ° C / W
( T J ( MAX ) ? T A ( MAX ) )
R TH ( J ? A )( MAX ) = =
Using this figure, and assuming T A(MAX) = 85°C, we can
calculate the maximum thermal impedance allowable to
maintain T J ≤ 150°C (see page 7):
P D ( MAX ) 1 . 81
R TH ( J ? C )( MAX ) = 3 ° C / W and R TH ( C ? S ) = 0 ° C / W ,
therefore R TH ( S ? A )( MAX ) = 33 ° C / W
This should be achievable for the TO-263 package using
pcb copper area to aid in conducting the heat away from
the device, such as a large (~2 squ. inch) pad connected
to the tab of the device. Internal ground/power planes
and air flow will also assist in removing heat. For higher
power dissipations it may be necessary to use a small
heatsink and the TO-220 package.
