LEDs
CxxxXT290-Sxx00-A
Cree’s XThin LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN materials
with Cree’s proprietary G•SiC® 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. These vertically structured LED chips are approximately 115 microns in height and
require a low forward voltage. Cree’s XT™ chips are tested for conformity to optical and electrical specifications and
the ability to withstand 1000V ESD. Applications for XThin LEDs include next-generation mobile appliances for use
in their LCD backlights and digital camera flash where brightness, sub-miniaturization, and low power consumption
are required.

Maximum ratings are package dependent. The above ratings were determined using a T-1 3/4 package (with Hysol OS4000
epoxy) for characterization. Ratings for other packages may differ. The forward currents (DC and Peak) are not limited by the die
but by the effect of the LED junction temperature on the package. The junction temperature limit of 125°C 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 325°C (< 5 seconds). See Cree Xthin Applications Note for more assembly process information.
Product resistance to electrostatic discharge (ESD) according to the HBM is measured by simulating ESD using a rapid avalanche
energy test (RAET). The RAET procedures are designed to approximate the maximum ESD ratings shown. The RAET procedure is
performed on each die. The ESD classification of Class 2 is based on sample testing according to MIL-STD-883E.
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 within the range of average values expected by manufacturer in large quantities and are provided for information only. All
measurements were made using lamps in T-1 3/4 packages (with Hysol OS4000 epoxy). Optical characteristics measured in an
integrating sphere using Illuminance E.
Back contact metal is 80%/20% Au/Sn by weight, with target eutectic melting temperature of approximately 282°C. See XBright®
Applications Note for detailed packaging recommendations.
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.
XThin chips are shipped with the junction side down, not requiring a die transfer prior to die attach.
