TR5270™ LEDs
Data Sheet

(175-μm)
CxxxTR5270-Sxx00-3
(250-μm)
Cree’s TR5270 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 TR5270 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 TR5270 is available in two chip
thicknesses: 175 µm and 250 µm. The 250-µm-thick version offers 5% improvement brightness over the 175-µm
version due the increased bevel area. The design is optimally suited for industry-standard 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).

(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.

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 (CxxxTR5270-Sxxxx or CxxxTR5270-Sxxxx-3 ) orders may be filled with any or all bins
(CxxxTR5270-xxxx or CXXXTR5270-xxxx-3) contained in the kit. All radiant flux and dominant wavelength values shown
and specified are at If = 120 mA.
