Description
Cree's RazerThin™ LEDs are a new generation of solid state LED emitters which combine highly
efficient InGaN materials with Cree's proprietary SiC substrate to deliver superior price performance for
high intensity blue and green LEDs. These vertically structured LED chips are approximately 95
microns in height and require a low forward voltage. Cree's RazerThin series chips have the ability to
withstand 1000V ESD. Applications for RazerThin include next generation 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 T-1 3/4 package (with Hysol
OS4000 epoxy) for characterization. Seller makes no representations regarding ratings for packages other than the T-1
3/4 package used by Seller. The forward currents (DC and Peak) are not limited by the G •SiC 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) is measured by simulating ESD using a rapid avalanche energy test
(RAET). The RAET procedures are designed to approximate the maximum ESD ratings shown. Seller gives no other
assurances regarding the ability of Products to withstand ESD.
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 the average values expected by Seller in large quantities and are provided for information only.
Seller gives no assurances Products shipped will exhibit such typical ratings. All measurements were made using lamps
in T-1 3/4 packages (with Hysol OS4000 epoxy). Dominant wavelength measurements taken using Illuminance E.
4. For reference only, typical Vf for C460, C470, and C527 is 3.2V and at 20mA.

Standard Bins for RT290:
All LED chips are sorted onto die sheets according to the bins shown below. All radiant flux values
shown and specified are at If = 20mA (see Note 1) and all dominant wavelength values shown and
specified are at If = 5mA (see Note 2).
Notes:
1) For reference only, radiant flux values at If = 5mA are typically 29% and 32% of the corresponding radiant flux at If =
20mA for 455-475nm range and 520-535nm range, respectively.
2) For reference only, wavelength values at If = 20mA are typically 2nm less and 7nm less than the corresponding
wavelength values at If=5mA for 455-475nm range and 520-535nm range, respectively.
