Mounting Note: When mounting ensure entire ceramic portion of case is mounted on a clean, flat heat sink with an appropriate
thermal interface, such as thermal grease. For screw mounting use of a compression washer at a force of 150 to 300lbs (665 to
1330N) is recommended without exceeding mounting torque of 8 in-lbs (0.9 N-m) to avoid package damage. For clip mounting use
of a round or smooth clip in contact area is recommended to avoid a concentrated hot spot on package.

The case temperature is to be used for the definition of the applied power limit
The case temperature measurement must be made with a thermocouple contacting the center of the component mounted on the designed heat sink
TR50/100 must be mounted to head sink using proper mounting clip for efficient heat dissipation
