In the above example, let’s say that the user’s load current is
200 mA and he wants to calculate the combined
q
C-S
and
q
S-A
he needs:
Given: I
O
= 200 mA,
= 11.75
°
C/W
Given
q
J-C
= 7.15

C/W for the 4194 in the K package,
q
C-S
+
q
S-A
= 11.75
°
C/W – 7.15
°

= 4.6
°
C/W
When using heatsink compound with a metal-to-metal
interface, a typical
q
C-S
= 0.5
°
C/W for the K package.
The remaining
q
S-A
of approximately 4
°
C/W is a large
enough thermal resistance to be easily provided by a number
of heatsinks currently available. Table 1 is a brief selection
guide to heatsink manufacturers.
