Application Information (continues)
Thermal resistance consists of two main elements,
Θ
jc
(junction to case) and
Θ
ca (case to ambient). Using the
power SOP-8 reduces
Θ
ca, the total thermal
resistance,
Θ
ja (junction to ambient) is the limiting
factor in calculating the maximum power dissipation
capability of the device. Typically, the power SOP-8
have a
Θ
jc of 20
o
C/W dramatically , this is significantly
lower than the standard SOP-8 which is typically
75
o
C/W.
Θ
ca is reduced because pin 5~8 can be
soldered directly to a ground plane which significantly
reduces the case to sink and sink to ambient thermal
resistance.
Power Dissipation
From under curves, the minimum area of copper
necessary for the par to operate safely can be
determined. The maximum allowable temperature rise
must be calculated to determine operation along
which curve.
