oPErating LiMits

The maximum current rating of the CXB1507 is dependent on the case temperature (Tc) when the LED has reached thermal equilibrium

under steady-state operation. The graphs shown below assume 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 Tc measurement point.
