Mounting High Power Devices
The mounting surface must be flat to less than 0.0254 mm (0.001 inch) and devoid of
scratches or burrs. The underside of the flange should be brushed with thermal
grease prior to being fastened to the heat sink with mounting screws. The thermal
grease will fill any air gaps and help to keep a good thermal contact.
Tabs (1 for Termination, 2 for Resistors)
Termination/Resistor
Circuit Board
Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place.
Heat Sink/Ground Plane
Flange
Ensure that the temperature on the surface of the flange does not exceed 110 ˚C when
running at 100 % of load. If the temperature increases then derate the power.
