Notes:
1. Maximum ratings are package-dependent. The above ratings were determined using a Cree SMT package (with silicone
encapsulation) for characterization. Ratings for other packages may differ. 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) 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.
3. All products conform to the listed minimum and maximum specifications for electrical and optical characteristics when assembled
and operated at 50 mA within the maximum ratings shown above. Efficiency decreases at higher currents. Typical values given
are within the range of average values expected by 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 encapsulant and silicone die attach). Optical
characteristics measured in an integrating sphere using Illuminance E.
