Maximum DC forward current is determined by the overall thermal resistance and ambient temperature. Follow the curves in Figure 11 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.
Solder conditions per JEDEC 020D. See Reflow Soldering Profile Figure 5.
5.
LED Engin recommends taking reasonable precautions towards possible ESD damages and handling the LZP-00H100 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 5:
1.
When operating the Blue LED, observe IEC 62471 Risk Group 2 rating. Do not stare into the beam.
2.
Viewing Angle is the off axis angle from emitter centerline where the luminous intensity is ½ of the peak value.
3.
Total Included Angle is the total angle that includes 90% of the total luminous flux.
