Mounting High Power Devices
The mounting surface must be flat to less
than 0.0254 mm (0.001 ”) 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.
Termination/Resistor
Tabs (1 for Termination, 2 for Resistors)

Heat Sink/Ground Plane
Flange
Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place.
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.
