3. Electro-Optical Characteristics @Tc=22℃
1) These values are measured by the DELI optical spectrum analyzer within the following tolerances.
--Forward Voltage (Vf): ±0.2V; peak wavelength (λp):±3nm; Radiant Flux (Φe):±10%
2) Although all LEDs are tested by DELI Semiconductor’s equipment. Some values may vary slightly
depending on the conditions of the test equipment.
3) UV LEDs are static-sensitive products. Please pay attention to static electricity during transportation and use;
4. Absolute Maximum Ratings

1) Operating the LED beyond the listed maximum ratings may affect device reliability
and cause permanent damage;
2) The light attenuation of the LED lamp will increase and the operation life will be shortened
as the injection current increases and the temperature rises;
3) The LEDs are not designed to be driven in reverse bias.
5. Outline Dimensions:
1) ①Cathode Pad ② Heat Sink ③Anode Pad;
2)The tolerance unless mentioned is ±0.20mm.unit=mm;
3)A Zener diode (not shown in the figure) is soldered inside the lamp to provide the ESD protection;

**Major security tips**
This product is a deep ultraviolet LED, which will produce ultraviolet light after the correct
operation of electricity. Thus it is harmful to the skin and eyes of the human body. No
protective measures should be avoided directly in deep ultraviolet light.
It is recommended to wear protective clothing,gloves and glass
