CREE C450TR5050-0207 Adhesive die attach low forward voltage 3.3 v typical at 120 ma Datasheet

TR5050™ LEDs
CxxxTR5050-Sxx000
Data Sheet
Cree’s TR5050 LEDs are the next generation of solid-state LED emitters that combine highly efficient InGaN materials
with Cree’s proprietary device technology and silicon-carbide substrates to deliver superior value for the TV-backlighting
and general-illumination markets. The TR5050 LEDs are among the brightest in the top-view market while delivering a
low forward voltage, resulting in a very bright and highly efficient solution. The design is optimally suited for industrystandard top-view packages.

Maximum ratings are package-dependent. The above ratings were determined using lamps in chip-on-MCPCB (metal core PCB)
packages for characterization. Ratings for other packages may differ. Junction temperature should be characterized in a specific
package to determine limitations. Assembly processing temperature must not exceed 325°C (< 5 seconds).
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.
All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 120 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 encapsulant and clear epoxy die attach).
Optical characteristics 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 CxxxTR5050-Sxx000
Radiant Flux (mW)
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 (CxxxTR5050-Sxxxx) orders may be filled with any or all bins (CxxxTR5050-xxxx) contained
in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 120 mA.
