1.PACKAGE
1)①③ Cathode Pad. ②④ Anode Pad. ⑤Heat Sink. ①~② a group. ③~④ a group.
2)The tolerance unless mentioned is ±0.20mm. unit=mm;
3)A single device contains three different types of chips, respectively UVA LED/UVC LED/ zener diode.
Zener diode is used to provide ESD to UVC LED
4)Internal Circuit diagram:
More information:
Note: It will affect the quality of the equipment,even broken if out of the limitation of the LED use confition.
It is not recommended to operate over the above limits

Absolute Maximum Ratings:
4.Instructions:
⑴LED storage: suggest to sealed stock in under the temperature of
10℃-55℃,
humidity of 30%-65%.In order tokeep a good quality, pls use it within 1 year after the prodcution
date;
and use it out within 28days after open the package.
⑵ When taking or touch the LED, pls make sure to wear the gloves.
Seal the package in time in orde to avoid the pin oxidation. When openning the package,
need to use the weezers clamped on both sides of LED in order not
to touch the face of the LED.
⑶ Installation: This process is mainly to protect the static
electricity:
① Check if the grounding wire of the machine equipment is normal
before production;
② Check if the static ring is normal, check static metal and human
skin contact closely;
③ Check if the workerswear anti-static gloves;
④ Check if the working table is paved with electrostatic rubber
cloth,
and the rubber cloth is connected to each other.
⑤ After opening the seal, it is better to use it out in 24hors,
otherwise it may cause the oxidation of the foot.
5.It is recommended to use low temperature solder paste for reflow,
and the temperature curve is shown in the following diagram.
① Preheating area
The temperature speed is 1.0-3.0℃/S. If the temperature rises too
fast, it is easy to cause
paste mobility and component deterioration, then cause the tin
explosive and phenomenon.
② Infiltrating area
The temperature is 110-130℃, 90-100s is the most suitable. If the
temperature is too low,
then the solder will not melt if it is rewelded. It is recommended
that the temperature rise speed is <2℃/ s.
③ Reflow Area
The peak temperature should be set at 170-180℃. The melting time
suggests to adjust to 50-80 seconds
when above 138℃
④ Cooling Area
Temperature cooling spead is better <4℃/ s.
⑸ With the increase of current and temperature, the life of LED
will decrease, which leads to the acceleration of the attenuation of LED.
⑹ It is suggested that a grounding circuit should be used in the
design of PCB. Pay special attention to the usage environment of LED: the temperature is between -30℃ to 55℃, and the
humidity is between 65%. Otherwise, the LED will be broken by electrostatic and high current breakdown.
6.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
