Beryllium oxide dust is toxic when inhaled. Care must be taken during handling and mounting to avoid damage to this area. These devices must never be thrown away with general industrial or domestic waste. .254 .045 .005 050-4927 Rev A 12-2004 Thermal Considerations and Package Mounting: Clamp ARF 1511 Heat Sink The rated 1500W power dissipation is only available when the package mounting surface is at 25C and the junction temperature is 200C. The thermal resistance between junctions and case mounting surface is 0.12C/W. When installed, and additional thermal impedance of 0.08C/W between the package base and the mounting surface is typical. Insure that the mounting surface is smooth and flat. Thermal joint compound must be used to reduce the effects of small surface irregularities. The heat sink should incorporate a copper heat spreader to obtain best results. The package is designed to be clamped to a heatsink. A clamped joint maintains the required mounting pressure while allowing for thermal expansion of both the device and the heat sink. A simple clamp and two 6-32 (M3.5) screw can provide the minimum 125lb required mounting force. T = 12 in-lb.
