Description
Cree's XBright
Plus
LEDs are the next generation of solid state LED emitters that combine highly
efficient InGaN materials with Cree's proprietary GSiC 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
XBright
Plus
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.

Notes:
1) Maximum ratings are package dependent. 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 a Photoresearch
Spectrascan Integrating Sphere. Illuminance E.
4)
All Products conform to the listed mechanical specifications within the tolerances shown.

Notes (continued):
5)
Back contact metal is 80%/20% Au/Sn by weight, with target eutectic melting temperature of approximately 282C. See XBright
Applications Note
for detailed packaging recommendations.
6)
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 XBright
Plus
:
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-Plus) orders may be filled with any or all bins (Cxxx-XB290-01xx-A) contained in the
kit.
