♦ENVIRONMENTAL  CHARACTERISTICS

-Lead Material: Tinned Copper.
-Without a heat sink.
-When in free air at 25,the TR20 is rated for 3W, TR30 is rated for 2.25W,  TR35 is rated for 2.5W and TR50 is rated for 3W  .
-The case temperature is to be used for the definition of the limit for power applied.
- The case temperature must be measured by contacting thermocouple to the center of the designed heat sink which is mounted on the component.
-Thermal grease should be applied properly.
