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
metal mounting surface, with the part properly mounted
and under electrical load. Without a heat sink, when in
free air at +25°C, the MP820, MP821, and MP850 are
rated for 2.25 watts, the MP825 is rated for 1.25 watts.
The thermal design should satisfy the following equation:
Case Temperature (Tc) + [Thermal Resistance (RθJC) x power applied (Watts)] ≤ TMAX considering the full
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 metal backface 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
variations 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
concentrating 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.
