Thermal Considerations and Package Mounting:
The rated 1500W power dissipation is only available when the package mounting
surface is at 25°C and the junction temperature is 200°C. The thermal resistance
between junctions and case mounting surface is 0.12°C/W. When installed, and
additional thermal impedance of 0.08°C/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.
HAZARDOUS MATERIAL
WARNING
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 industri-
al or domestic waste.
