Thermal Considerations and Package
Mounting:
The rated 1350W 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 instal-
led, an additional thermal impedance of 0.1°C/W
between the package base and the mounting sur-
face is typical. Insure that the mounting surface
is smooth and flat. Thermal joint compound
must be used to reduce the effects of small sur-
face irregularities. The heatsink should incorpo-
rate a copper heat spreader to obtain best re-
sults. Use 4-40 or M3 screws torqued to 1.2 Nm.
HAZARDOUS MATERIAL WARNING
The ceramic portion of the device between
leads and mounting surface is beryllium oxide-
BeO. Beryllium oxide dust is toxic when in-
haled. 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.
