... The figure below left shows the relationship between area and thermal resistance when an aluminum plate is used in the thermal design. The radiation characteristics of an aluminum plate can be improved by painting the surface in black. This can reduce the thermal resistance by 20% for a given surface area. c-a – S Heat sink area, S – cm j-c and Tj max for the STK732C Parameter j-c Tj max PTR (FET) 3.5° ...
