... Note that the ambient temperature is greatly influenced by the ventilation and air flow patterns within the application. This means that the size of the heat sink must be determined with care so that the STK672-210 back surface (aluminum substrate) temperature Tc in the mounted state never exceeds, under any conditions that might occur, the temperature Tc = 105 ° ...

... OH for the STK672-210 by comparison with the ∆Tc vs. Pd graph. Note that it is necessary to check the temperature rise in the actual application system case, since the STK672-210 substrate temperature Tc changes with the air convection conditions around the STK672-210 when a heat sink without fins is used. ...
