Thermal Resistance and Temperature Considerations:
Because the MW16 heat sink is not easily accessible to a temperature measurment the
thermal resistance is defined as R
l Calculation of Junction Temperature T
l Measurment of Case Temperature T

T
Tc should be measured in operation at the upper side of the case where the temperature
is highest. Small thermoelements 1mm (thin wires, thermopaste) and thermopapers
with low heat dissipation are well suited.
