A ceramic mid-power ultraviolet (UVC) emitting diode for sterilisation, sanitation, and purification applications has been released by Vishay Intertechnology. Featuring a quartz window, the Vishay Semiconductors VLMU35CM..-280-120 delivers an extremely long lifetime in a compact 3.5mm by 3.5mm by 1.2mm surface-mount package.
Designed to replace mercury UVC lamps, the device offers an emission angle of ± 60° and radiant power to 18mW at 100mA without the need for an external lens.
Built on AlGaN technology, the diode features forward current up to 150mA, forward voltage down to 4V, and a wavelength range of 270nm to 290nm.
RoHS-compliant, halogen-free, and Vishay Green, the VLMU35CM..-280-120 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
Samples of the new UVC emitting diode are available now. Production quantities are available with lead times of four weeks.
