Description
Cree's XB
TM
series of XBright
TM
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 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.

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 an integrating sphere. Illuminance E.

Notes (continued):
4)
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.
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-XB290-
01xx-A) contained in the kit.
