Once the value of P
D(max)
is known, the maximum permis-
sible value of R
Q
JA
can be calculated:
R
Q
JA
=
(2)
The value of R
JA
can then be compared with those in
the package section of the data sheet. Those packages with
R
JA
's less than the calculated value in equation 2 will
keep the die temperature below 150C.
In some cases, none of the packages will be sufficient to
dissipate the heat generated by the IC, and an external
heatsink will be required.
A heat sink effectively increases the surface area of the
package to improve the flow of heat away from the IC and
into the surrounding air.
Each material in the heat flow path between the IC and
the outside environment will have a thermal resistance.
Like series electrical resistances, these resistances are
summed to determine the value of R
Q
JA
:
R

JA
= R
Q

where:
R
Q
JC
= the junctionDtoDcase thermal resistance,
R
Q
CS
= the caseDtoDheatsink thermal resistance, and
R
Q
SA
= the heatsinkDtoDambient thermal resistance.
R
Q
JC
appears in the package section of the data sheet. Like
R
JA
, it too is a function of package type. R
CS
and R
SA
are functions of the package type, heatsink and the inter-
face between them. These values appear in heat sink data
sheets of heat sink manufacturers.
