*4 Case temperature (T
C
) and heatsink temperature (T
s
) is measured on the surface
(mounting side) of the baseplate and the heatsink side just under the chips.
Refer to the figure to the right for chip location.
The heatsink thermal resistance should be measured just under the chips.
*7 Typical value is measured by using thermally conductive grease of λ = 0.9 [W/(m • K)].
*8 Baseplate (mounting side) flatness measurement points (X, Y) are shown in the figure below.
