Generation II LEDs
CxxxMB290-Sxx00
Cree’s MB™ Generation II series of MegaBright LEDs combine highly efficient InGaN materials with Cree’s
proprietary G•SiC® substrate to deliver superior price/performance for high-intensity LEDs. These LED chips have a
geometrically enhanced vertical chip structure to maximize light extraction efficiency and require only a single wire
bond connection. Sorted die kits provide die sheets conveniently sorted into wavelength and radiant flux bins. Cree’s
MB series chips are tested for conformity to optical and electrical specifications and the ability to withstand 1000V
ESD. These LEDs are useful in a broad range of applications such as outdoor full-motion LED video signs, automotive
lighting and white LEDs, yet can also be used in high-volume applications such as LCD backlighting. Cree’s MB series
chips are compatible with most radial and SMT LED assembly processes.

Maximum ratings are package dependent. The above ratings were determined using a T-1 3/4 package (with Hysol OS4000
epoxy) 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).
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. The RAET procedure is
performed on each die. The ESD classification of Class 2 is based on sample testing according to MIL-STD-883E.
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 the 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). Dominant wavelength measurements
taken using Illuminance E.
Caution: To obtain optimum output efficiency, the maximum height of die attach epoxy on the side of the chip should not exceed
80 μm.
