HAZARDOUS MATERIAL
WARNING
The ceramic portion of the
device between leads and
mounting surface is beryllium
oxide. Beryllium oxide dust is
highly 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:
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, an addi-
tional thermal impedance of 0.09 ˚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, a compliant layer of plastic or rubber, and two 6-32
(M3.5) screws can provide the minimum 85 lb required mounting force. T = 6 in-lb.
