PRODUCT FAMILY DATA SHEET
Cree® J Series® 2835 LEDs
PRODUCT DESCRIPTION
FEATURES
J Series® LEDs extend Cree’s industry‑leading portfolio of
• Industry‑compatible size : 2.8 x 3.5 x 0.7 mm
lighting‑class LEDs to a broader set of applications. The J Series
• 3‑V configuration
2835 LEDs combine high efficacy and excellent value in a reliable
• Flux binned at 25 °C, chromaticity binned at 85 °C
package. The J Series 2835 Standard LEDs are optimized
• 6500 K–2700 K ANSI CCTs available
for low‑density lighting applications where high efficacy and
• 70, 80 & 90 CRI available for all CCTs
smooth appearance are critical, such as downlights, troffers,
• 95 CRI minimum available for 5000 K, 4000 K, 3500 K,
and panel lights. The J Series 2835 Fidelity LEDs offer high CRI
3000 K & 2700 K
and are optimized for lighting applications where good color
• RoHS and REACH compliant
quality is critical.
• UL® recognized component (E495478)

Notes:
• Cree Venture maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and
±2 on CRI measurements. See the Measurements section (page 21).
• Cree Venture J Series 2835 LED order codes specify only a minimum flux bin and not a maximum. Cree Venture may ship reels in flux
bins higher than the minimum specified by the order code without advance notice. Shipments will always adhere to the chromaticity
restrictions specified by the order code.
◊ CRI R9 minimum is 0 for 80 CRI minimum LEDs and 50 for 90 CRI minimum LEDs, with a ±3 tolerance.
* Flux values @ 85 °C are calculated and for reference only.
** Contact your Cree sales representative for kitted 3‑step order code details.

REFLOW SOLDERING CHARACTERISTICS
In testing, Cree Venture has found J Series 2835 LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed below. As
a general guideline, Cree Venture recommends that users follow the recommended soldering profile provided by the manufacturer of the
solder paste used, and therefore it is the lamp or luminaire manufacturer’s responsibility to determine applicable soldering requirements.
Note that this general guideline may not apply to all PCB designs and configurations of reflow soldering equipment.

NOTES
Measurements
The luminous flux, radiant power, chromaticity, forward voltage and CRI measurements in this document are binning specifications only
and solely represent product measurements as of the date of shipment. These measurements will change over time based on a number
of factors that are not within Cree Venture’s control and are not intended or provided as operational specifications for the products.
Calculated values are provided for informational purposes only and are not intended or provided as specifications.
Pre‑Release Qualification Testing
Please read the J Series Reliability Overview for the details of the pre-release qualification testing for J Series LEDs.
Lumen Maintenance
Cree Venture uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED lumen
maintenance. For information on the specific LM-80 data sets available for this LED, refer to the public J Series LM-80 results document.
Please read the Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect
the LED junction temperature.
Moisture Sensitivity
Cree Venture recommends keeping J Series 2835 LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately
prior to soldering. Unopened MBP that contains J Series 2835 LEDs does not need special storage for moisture sensitivity.
Once the MBP is opened, J Series 2835 LEDs should be handled and stored

conditions listed below.
Baking Conditions
It is not necessary to bake all J Series 2835 LEDs. Only the LEDs that meet all of the following criteria must be baked:
1. LEDs that have been removed from the original MBP.
2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above.
3. LEDs that have not been soldered.
LEDs should be baked at 60 ºC for 24 hours. LEDs may be baked in the original reels. Remove LEDs from the MBP before baking. Do
not bake parts at temperatures higher than 60 ºC. This baking operation resets the exposure time as defined in the Moisture Sensitivity
section above.
