Cooling Plate
Where a cooling surface is available, a cooling plate
(option B, or option B1) can be used instead of the
standard heatsink. The mounting system must ensure suf-
ficient cooling capacity to guarantee that the maximum
case temperature
TC max is not exceeded. The required
cooling capacity can be calculated by the following
formula:
