XLAMP CMU2236 LED CHARACTERISTICS Characteristics Unit Minimum Typical Maximum Viewing angle (FWHM) degrees 115 ESD withstand voltage (JEDEC JS-001-2012) V Class 3A DC forward current mA 2640* Reverse current mA 0.1 Forward voltage ( 990mA, 85C) V 33.7 37.5 Forward voltage ( 990mA, 25C) V 34.4 38.2 * Refer to the Operating Limits section. OPERATING LIMITS The maximum current rating of the CMU2236 depends 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. Either solder pad shown in the Mechanical Dimensions section on page 15 can be used as 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 140C to ensure optimal LED lifetime. Please refer to the Thermal Design section on page 16 for more information on LES temperature measurement.
