XLAMP CXB1520 LED CHARACTERISTICS Characteristics Unit Minimum Typical Maximum Viewing angle (FWHM) degrees 115 ESD withstand voltage (HBM per Mil-Std-883D) V 8000 DC forward current mA 1400* Reverse current mA 0.1 Forward voltage ( 500mA, 85C) V 33 37 * Refer to the Operating Limits section. OPERATING LIMITS The maximum current rating of the CXB1520 depends on the case temperature (Tc) when the LED has reached thermal equilibrium under steady-state operation. 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 Tc measurement point. Another important factor in good thermal management is the temperature of the Light Emitting Surface (LES). Cree LED recommends a maximum LES temperature of 135C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 16 for more information on LES temperature measurement.
