Description
Cree's MB
series of MegaBright LEDs combine highly efficient InGaN materials with Cree's
proprietary GSiC substrate to deliver superior price performance for high intensity UltraViolet LEDs.
These LED chips have a geometrically enhanced vertical chip structure to maximize light extraction
efficiency, and require only a single wire bond connection. Cree's MB series chips are tested for
conformity to optical and electrical specifications and the ability to withstand 400V ESD. These LEDs
are useful in a broad range of applications such as white light applications and counterfeit bill detection,
yet can also be used in high volume applications. Cree's MB series chips are compatible with most radial
and SMT LED assembly processes.

Notes:

1)
Maximum ratings are package dependent. The above ratings were determined using a T-1 3/4 package with Hysol OS1600 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 GSiC
die but by the effect of the LED junction temperature on the package. The junction temperature limit of 125C 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 325C (< 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 20
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 OS1600 epoxy.

4)
All Products conform to the listed mechanical specifications within the tolerances shown.

5)
Caution: To obtain optimum output efficiency, the maximum height of die attach epoxy on the side of the chip should not exceed 80
m.
