TR2436™ LEDs
Data Sheet
CxxxTR2436-Sxx00
Cree’s TR™ LEDs are the newest 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 LCD sideview
market. The TR LEDs are among the brightest in the sideview market while delivering a low forward voltage resulting
in a very bright and highly efficient solution for the 0.4-mm, 0.6-mm and 0.8-mm sideview market. The design is
optimally suited for industry standard sideview packages as it is die attachable with clear epoxy and has two top
contacts, consistent with industry standard packaging.

Notes:
1. Maximum ratings are package dependent. The above ratings were determined using a T-1 3/4 package (with Hysol OS4000 epoxy
encapsulation and clear epoxy die attach) 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).
2. 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.
3. 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 encapsulant and clear epoxy die attach).
Optical characteristics measured in an integrating sphere using Illuminance E.

Standard Bins for CxxxTR2436-Sxx00
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 (CxxxTR2436-Sxxxx) orders may be filled with any or all bins (CxxxTR2436-xxxx) contained
in the kit. All radiant flux and dominant wavelength values shown and specified are at If = 20 mA.
