Cree® EZ1000™ Gen II LEDs
Data Sheet
CxxxEZ1000-Sxx000-2
Cree’s EZBright™ LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN
materials with Cree’s proprietary optical design and device submount technology to deliver superior value for highintensity LEDs. The optical design maximizes light extraction efficiency and enables a Lambertian radiation pattern.
Additionally, these LEDs are die-attachable with conductive epoxy, solder paste or solder preforms, as well as the flux
eutectic method. These vertically structured, low forward voltage LED chips are approximately 170 microns in height.
Cree’s EZ™ chips are tested for conformity to optical and electrical specifications. These LEDs are useful in a broad
range of applications such as general illumination, automotive lighting, and LCD backlighting.

Maximum ratings are package-dependent. The above ratings were determined using a 3.45 x 3.45 mm SMT package without an
encapsulant for characterization. Ratings for other packages may differ. The junction temperature should be characterized in a
specific package to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds). See Cree
EZBright Applications Note for assembly-process information.
All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 350 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given
are within the range of average values expected by the manufacturer in large quantities and are provided for information only. All
measurements were made using a Au-plated TO39 header without an encapsulant. Optical characteristics were measured in an
integrating sphere using Illuminance E.
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for
the end-product to be designed in a manner that minimizes the thermal resistance from the LED junction to ambient in order to
optimize product performance.

Standard Bins for CxxxEZ1000-Sxx000-2
LED chips are sorted to the radiant flux and dominant wavelength bins shown. A sorted die sheet contains die from
only one bin. Sorted die kit (CxxxEZ1000-Sxx000-2) orders may be filled with any or all bins (CxxxEZ1000-0xxx-2)
contained in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 350 mA. Radiant
flux values are measured using Au-plated TO39 headers without an encapsulant.
