D1 D3 .100 .175 D1 D3 HAZARDOUS MATERIAL WARNING G3 G1 G3 1.065" 27.05 mm S1D2 ARF1511 S3D4 .100 .075 .100 .175 G1 S1D2 S3D4 G2 G2 S2 G4 S4 .100 .075 .100 G4 .300 1.065" 27.05 mm .300 S2 S4 The ceramic portion of the device between leads and mounting surface is beryllium oxide, BeO. 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. Thermal Considerations and Package Mounting: .254 .045 .005 050-4927 Rev D 10-2008 The rated 1500W power dissipation is only available when the package mounting surface is at 25C and the junction temperature is 175C. The thermal resistance between junctions and case mounting surface is 0.10C/W. When installed, an additional thermal impedance of 0.06C/W between the package base and the mounting surface is smooth and flat. Thermal joint compound must be used to reduce the effects of small surface irregularities. The heatsink 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) screws can provide the minimum 125 lb. required mounting force. T=4-6 in-lb. Please refer to App Note 1802 "Mounting Instructions for Flangeless Packages."
