CREE C450EZ700-0312-2 Ezbright power chip led rf performance low forward voltage â 3.6 v typical at 350 Datasheet

Cree® EZ700™ Gen II LED
Data Sheet
CxxxEZ700-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 technology to deliver superior value for high-intensity 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, in addition to using 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 Au-plated TO39 header 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 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 measured in an
integrating sphere using Illuminance E.
This peak forward current specification is based on a 400-ms pulse width at a 1/5-duty cycle with a junction temperature of
65°C.

Standard Bins for CxxxEZ700-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 (CxxxEZ700-Sxx000-2) orders may be filled with any or all bins (CxxxEZ700-0xxx-2)
contained in the kit. All radiant flux and all dominant wavelength values shown and specified are at If = 350 mA. Radiant
flux values are measured using Au-plated TO39 headers without an encapsulant.
