Maximum DC forward current is determined by the overall thermal resistance and ambient temperature.
Follow the curves in Figure 10 for current derating.
2:
Pulse forward current conditions: Pulse Width ≤ 10msec and Duty Cycle ≤ 10%.
3.
LEDs are not designed to be reverse biased.
4.
Autoclave Conditions per JEDEC JESD22-A102-C.
5.
LED Engin recommends taking reasonable precautions towards possible ESD damages and handling the LZ4-00UA00
in an electrostatic protected area (EPA). An EPA may be adequately protected by ESD controls as outlined in
ANSI/ESD S6.1.

Notes for Table 7:

The standard soak time is the sum of the default value of 24 hours for the semiconductor manufacturer’s exposure time (MET) between bake and bag
and the floor life of maximum time allowed out of the bag at the end user of distributor’s facility.
Average Radiant Flux Maintenance Projections
Lumen maintenance generally describes the ability of an emitter to retain its output over time. The useful lifetime
for power LEDs is also defined as Radiant Flux Maintenance, with the percentage of the original light output
remaining at a defined time period.
Based on long-term WHTOL testing, LED Engin projects that the LZ Series will deliver, on average, 70% Radiant Flux
Maintenance (RP70%) at 20,000 hours of operation at a forward current of 700 mA per die. This projection is
based on constant current operation with junction temperature maintained at or below 80°C.
