Proper current derating must be observed to maintain the junction temperature below the maximum allowable junction temperature. 2. Residual periodic variations due to power conversion from alternating current (AC) to direct current (DC), also called “ripple,” with frequencies ≥100Hz and amplitude ≤15% of the maximum allowable DC forward current are acceptable, assuming the average current throughout each cycle does not exceed the maximum allowable DC forward current at the corresponding maximum junction temperature. 3. Pulsed operation with a peak drive current equal to the stated peak pulsed forward current is acceptable if the pulse on-time is ≤5ms per cycle and the duty cycle is ≤50%. 4. Transient reverse voltages and surge currents due to electrical switching or supply interruptions are acceptable if these events do not last for more than 10ms, the amplitude of the reverse voltage does not exceed 5V and the reverse current is less than 220uA 5. Max 5V reverse for up to 10s is an acceptable beginning of life, one time test condition. DS133 LUXEON TX Product Datasheet 20180516 ©2018 Lumileds Holding B.V. All rights reserved. 4

Product Bin and Labeling Definitions Decoding Product Bin Labeling In the manufacturing of semiconductor products, there are variations in performance around the average values given in the technical datasheet. For this reason, Lumileds bins LED components for luminous flux or radiometric power, color point, peak or dominant wavelength and forward voltage. LUXEON TX LEDs are labeled using a 4-digit alphanumeric CAT code following the format below: A B C D A – designates luminous flux bin (example: M=210 to 220 lumens, R=250 to 260 lumens) B – designates correlated color temperature bin (1=6500K, 2=5700K, 3=5000K, 5=4000K, 6=3500K, 7=3000K, 8=2700K) C – designates SDCM bin (3=3-step MacAdam ellipse, 5=5-step MacAdam ellipse) D – designates forward voltage bin (example: P=2.50 to 2.75V, R=2.75 to 3.00V) Therefore, a LUXEON TX with a lumen range of 210 to 220, color bin of 7 for 3000K parts, 3-step MacAdam ellipse 80CRI and a forward voltage range of 2.50 to 2.75 has the following CAT code: M 7 3 P Luminous Flux Bins Table 5 lists the standard luminous flux bins for LUXEON TX emitters. Although several bins are outlined, product availability in a particular bin varies by production run and by product performance. Not all bins are available in all CCTs. Table 5.
