Maximum DC forward current (per die) 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 3.
5.
Autoclave Conditions per JEDEC JESD22-A102-C.
6.
LED Engin recommends taking reasonable precautions towards possible ESD damages and handling the LZ4-00R508 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.
Radiant flux typical value is for all four LED dice operating concurrently at rated current.
2.
This product emits non visible infrared light, which can be hazardous depending on total system configuration (including, but not limited to optics, drive
current and temperature). Observe safety precaution given in IEC 62471 when operating this product.
3.
Viewing Angle is the off axis angle from emitter centerline where the radiant power is ½ of the peak value.
4.
Total Included Angle is the total angle that includes 90% of the total radiant flux.
