Mounting Note: Mount on a smooth, clean, and flat heat sink surface with a thermal interface material, such
as thermal grease. The entire exposed ceramic portion must be in thermal contact with the heat sink. When
screw mounting, use a compression washer which provides a mounting force of 150 to 300 pounds (665 to
1330 N). This will provide sufficient pressure on the package over time and through large temperature varia-
tions to maintain the maximum power dissipation capability. Mounting torque to avoid package damage is 8
in-lbs. (0.90 N-m). If a spring clip is used, a clip force of 8 to 30 pounds (35 to 130 N) is recommended to be
applied to the center of the package. The clip should be round or smooth in the contact area to avoid concen-
trating the load on a small point of the plastic body of the package. Another mounting option is to use a
pressure bar method which can achieve a greater mounting force with a greater contact area.
For additional applications information regarding mounting and pulse handling see the Caddock
Applications Notes at caddock.com or contact Applications Engineering.
