The R
θ
CS values are estimates for dry mounting with heatsinks contacting the
raised pedestal on the package. For minimum thermal resistance, the device
should be sandwiched between clean, flat, smooth conducting electrodes and
securely held in place with a compressive force of 2 pounds maximum. The
electrodes should contact the entire pedestal area. When the device is
mounted symmetrically, the thermal resistances are identical. The values for
R
θ
SA and R
θ
CS are controlled by the user and depend on heatsink design and
mounting conditions.
Thermal resistance values are:
