UT170 Gen 3

Cree® UltraThin® Gen 3 LEDs
Data Sheet
CxxxUT170-Sxxxx-31
Cree’s UltraThin® LEDs combine highly efficient InGaN materials with Cree’s proprietary G•SiC® substrate to deliver
superior price/performance for blue LEDs. These vertically structured LED chips are small in size and require a low
forward voltage. Cree’s UT™ series chips are tested for conformity to optical and electrical specifications and the
ability to withstand 1000 V ESD. Applications include keypad backlighting where sub-miniaturization and thinner
form factors are required.

Notes:
1. Maximum ratings are package dependent. The above ratings were determined using a thru-hole package (with Hysol® OS4000
encapsulant) 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 thru-hole 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 minimum ESD ratings shown. The ESD classification
of Class 2 is based on sample testing according to MIL-STD-883E.
3. All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 5 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 thru-hole packages (with Hysol OS4000 encapsulant). The amount of die attach
adhesive used will affect light output; it is recommended that the adhesive amount be optimized to meet the requirements of each
specific application. Optical characteristics measured in an integrating sphere using Illuminance E.
4. Bonding Area is defined as the bond pad area exposed through the opening in the passivation layer.
5. Specifications are subject to change without notice.
