Maximum ratings are package-dependent. The above ratings were determined using a chip sub-mount on MCPCB (with silicone encapsulation and
intrinsic AuSn metal die attach) 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).
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.
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 intrinsic AuSn metal die attach). Optical characteristics measured in an integrating sphere
using Illuminance E.
The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is crucial for the end-product to be
designed in a manner that minimizes the thermal resistance from the LED junction to ambient in order to optimize product performance.
