Description
Cree's MB™ series of MegaBright LEDs combine highly efficient InGaN materials with Cree's
proprietary G⋅SiC® substrate to deliver superior price/performance for high intensity blue and green
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.
