Thermal Considerations and Package Mounting:
The rated power dissipation is only available when the
package mounting surface is at 25°C and the junction temperature is 175°C. The thermal resistance between junctions and case mounting surface is 0.3°C/W. When installed, an additional thermal impedance of 0.1°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. Use the minimum amount necessary
to coat the surface. The heatsink should incorporate a copper heat spreader to obtain best results.
The package design clamps the ceramic base to the
heatsink. A clamped joint maintains the required mounting
pressure while allowing for thermal expansion of both the
base and the heat sink. Four 4-40 (M3) screws provide
the required mounting force. Torque the mounting screws
to 6 in-lb (0.68 N-m).
