Description
DUV-SMD
is a series of
AlGaN
based single emitter DEEP-UV LEDs in a ceramic 3020 SMD package, is ready for reflow soldering
process, and can be delivered on tape. It features an integrated ESD protection device and quartz glass window.
DUV-SMD
is
available from 265 nm up to 340 nm peak wavelength with an optical output power of typically 1mW.

Precautions
Soldering:
Recommended soldering profile
Recommended solder pad layout
all dimensions in mm
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
