The underside of the fl ange should be brushed with thermal grease prior to being fastened to the heat sink with mounting screws. The thermal grease will fi ll 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. Ensure that the temperature on the surface of the fl ange does not exceed 110 ˚C when running at 100 % of load. If the temperature increases then derate the power.
