Description
The LZ4-00UA10 UV LED emitter provides superior radiometric power in the wavelength range
specifically required for sterilization, dental curing lights, and numerous medical applications.
With a 7.0mm x 7.0mm x 4.3mm ultra-small footprint, this package provides exceptional optical
power density. The radiometric power performance and optimal peak wavelength of this LED
are matched to the response curves of many dental resins, resulting in a significantly reduced
curing time. The patent-pending design has unparalleled thermal and optical performance. The
high quality materials used in the package are chosen to optimize light output, have excellent
UV resistance, and minimize stresses which results in monumental reliability and radiant flux
maintenance.

Notes for Table 5:
1. 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. LedEngin recommends taking reasonable precautions towards possible ESD damages and handling the LZ4-00UA10
in an electrostatic protected area (EPA). An EPA may be adequately protected by ESD controls as outlined in
ANSI/ESD S6.1.
