The graph shown below assumes that the system design employs good thermal management (thermal interface material and heat sink) and may vary when poor thermal management is employed. Please refer to the Mechanical Dimensions section on page 15 for the location of the CXA2520 Tc measurement point. 1500 1250 1000 750 500 250 0 0 25 50 75 100 125 150 Case Temperature (C) Copyright 2012-2017 Cree, Inc.
