The worst case temperature rise from case to ambient is given by the equation:
where:
θ
SA Theta sink to ambient
θ
CS Theta case to sink
Τ
A(MAX) Air temperature, user supplied (typically 55
o C)
Τ
C(MAX) Case temperature (85
oC for Industrial range)
TT
C - TA
P
(MAX) Power (2.0 W for VS8061)
Ιf T
A = 55
o C and
θ
CS (user supplied) is typically 0.6
o C/W,
Therefore, to maintain the proper case and junction temperature, a heat sink with a
θ
SA of 14.4
o C/W or less
must be selected at the appropriate air flow.
Note: the heat spreader is tied to V
EE in both the VS8061 and VS8062.
