The thermal design should satisfy the following equation:
Case Temperature (T c ) + [Thermal Resistance (R θJC ) x power applied (Watts)] ≤ T
operating temperature range of the application.
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.

All power and associated overload ratings are derated
based upon case temperature using the derating curve.
The case temperature is measured at the center of the
ceramic mounting surface, with the part properly
mounted and under electrical load. Without a heat sink,
when in free air at +25°C, the MP915 is rated for 1.25
watts, the MP916, MP925, MP930 are rated for 2.25
watts, and the MP9100 is rated for 3.5 watts.
