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. Pre-tin the tab prior to installation. Position the tab over the circuit and solder in place. Heat Sink/Ground Plane Flange Termination/Resistor Tabs (1 for Termination, 2 for Resistors) Circuit Board 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. 10/09 Specifications are subject to change without notice. Customers should verify actual device performance in their specific applications
