Ceramic/Quartz Diode Supplants Mercury UVC Lamps

Poised for sterilization, sanitation, and purification applications, Vishay Intertechnology’s ceramic- and quartz-based short wavelength ultraviolet (UVC) emitting diode is designed to replace mercury UVC lamps. The VLMU60CL..-280-125 delivers an extremely long lifetime in a 6 mm x 6 mm x 1.6 mm surface-mount package.


Comparable to devices in a PLCC2 package with emission angles of ± 60°, the device offers an emission angle of ± 62.5° and high radiant power to 3.8 mW at 20 mA without the need for an external lens. Built on AlGaN technology, the VLMU60CL..-280-125 features forward current to 40 mA, forward voltage down to 4.4 V, and a wavelength range of 270 nm to 290 nm.
