Description
UVLUX250-3
is a series of
AlGaN
based deep UV multi chip LED arrays, utilizing 4 parallel connected chip dies, with a typical peak
wavelength of
255 nm
and optical output power of
1-3 mW.
It comes in hermetically sealed TO39 metal can package with
hemispherical lens or flat glass window.
UVLUX250-3
is widely used for forensic analysis, disinfection, optical sensing, and imaging
applications

Precautions
Soldering:
•
•
•
•
•
•
•
•
•
•
Do avoid overheating of the LED
Do avoid electrostatic discharge (ESD)
Do avoid mechanical stress, shock, and vibration
Do only use non-corrosive flux.
Do only solder the leads. Soldering of header or cap will damage the LED
Do only cut the leads at room temperature with an ESD protected tool
Do not solder closer than 3 mm from base of the header
Do form leads prior to soldering
Do not impose mechanical stress on the header when forming the leads
Do not apply current to the LED until it has cooled down to room temperature after soldering
Recommended soldering conditions:

It is strongly advised to perform soldering at the shortest time and lowest temperature
possible.
Cleaning:
Cleaning with isopropyl alcohol, propanol, or ethyl alcohol is recommended
DO NOT USE acetone, chloroseen, trichloroethylene, or MKS
DO NOT USE ultrasonic cleaners
Static Electricity:
UVTOP are sensitive to electrostatic discharge (ESD).
Precautions against ESD must be taken when handling or
operating these LEDs. Surge voltage or electrostatic discharge can result in complete failure of the device.
UV-Radiation:
During operation these LEDs do emit
high intensity ultraviolet light,
which is hazardous to skin and eyes, and may
cause cancer. Do avoid exposure to the emitted UV light.
Protective glasses are recommended.
It is further advised
to attach a warning label on products/systems that do utilize UV-LEDs:
Class 1
Operation:
Do
only
operate UVTOP LEDs with a current source.
Running these LEDs from a voltage source
will
result in complete failure of the device.
Current of a LED is an exponential function of the voltage across it. Usage of current regulated drive circuits is
mandatory
