Example of fin mounting
The fin is formed into such a shape as to be able to radiate heat from the plastic fin area of IC and the fin as shown below and is
soldered to the printed circuit board. For the fin size, refer to the Pd max-Ta characteristics. The desirable material is copper or
iron which is solderable. It is recommended to apply silicone grease, etc. to the plastic area of IC in order to minimize the thermal
resistance.
