G*SiC(R) Technology XBrightTM LEDs Cxxx-XB290-S0100-A Features * Applications XBrightTM Performance * Outdoor LED Video Displays - 12.0 mW min Blue (460nm and 470nm) * Automotive Dashboard Lighting - 7.0 mW min Green (527nm) * White LEDs * Single Wire Bond Structure * Class II ESD Rating * Backlighting Description Cree's XBTM series of XBrightTM LEDs are the next generation of solid state LED emitters that combine highly efficient InGaN materials with Cree's proprietary G*SiC(R) substrate to deliver superior price performance for high intensity LEDs. These LED chips have a geometrically enhanced Epi-down design to maximize light extraction efficiency, and require only a single wire bond connection. Cree's XB series chips are tested for conformity to optical and electrical specifications and the ability to withstand 1000V ESD. These LEDs are useful in a broad range of applications such as outdoor full motion LED video signs, automotive lighting and white LEDs, yet can also be used in high volume applications such as LCD backlighting.

The above ratings were determined using a T-1 3/4 package (with Hysol OS4000 epoxy) for characterization. Seller makes no representations regarding ratings for packages other than the T-1 3/4 package used by Seller. The forward currents (DC and Peak) are not limited by the G *SiC die but by the effect of the LED junction temperature on the package. The junction temperature limit of 125C is a limit of the T-1 3/4 package; junction temperature should be characterized in a specific package to determine limitations. Assembly processing temperature must not exceed 325C (< 5 seconds). See Cree XBright Applications Note for more assembly process information. 2) Product resistance to electrostatic discharge (ESD) is measured by simulating ESD using a rapid avalanche energy test (RAET). The RAET procedures are designed to approximate the maximum ESD ratings shown. Seller gives no other assurances regarding the ability of Products to withstand ESD. 3) All Products conform to the listed minimum and maximum specifications for electrical and optical characteristics, when assembled and operated at 20 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given are the average values expected by Seller in large quantities and are provided for information only. Seller gives no assurances Products shipped will exhibit such typical ratings. All measurements were made using lamps in T-1 3/4 packages with Hysol OS4000 epoxy. Optical characteristics were measured in an integrating sphere. Illuminance E. CPR3BC Rev. D (c) Cree, Inc. 2003 All Rights Reserved.

See XBright Applications Note for detailed packaging recommendations. 5) Caution: To avoid leakage currents and achieve maximum output efficiency, die attach material must not contact the side of the chip. See Cree XBright Applications Note for more information. Standard Bins for XB290: LED chips are sorted to the radiant flux and dominant wavelength bins. A sorted die sheet contains die from only one bin. Sorted die kit (Cxxx-XB290-S0100-A) orders may be filled with any or all bins (Cxxx-XB29001xx-A) contained in the kit.
