Description
DUV-HL18W
is a series of
AlGaN
based single emitter DEEP-UV LEDs in a hermetically sealed TO18 package, utilizing a
hemispherical quartz glass lens with beam angle of 40 degree.
DUV-HL18W
is available from 265 nm up to 340 nm peak
wavelength with an optical output power of typically 0.8 mW.

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
Static Electricity:
LEDs 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 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
