New ceramic/quartz-based UVC emitting diode delivers exceptionally long lifetime

Vishay Intertechnology offers a new ceramic/quartz-based UVC (short wavelength ultraviolet) emitting diode for sanitation, sterilisation, and purification applications. Developed to replace mercury UVC lamps, the Vishay Semiconductors VLMU60CL..-280-125 deliver a long lifetime in a 6mm x 6mm x 1.6mm surface-mount package. Comparable to devices in the PLCC2 package with emission angles of ±60-degrees, the device offers an emission angle of ±62.5-degrees and high radiant power to 3.8mW at 20mA without the need for an external lens. Built on AlGaN technology, the device features forward current to 40mA, forward voltage down to 4.4V, and a wavelength range of 270nm to 290nm. The emitter diode's specifications make it ideal for water and air purification, physical surface sterilisation, medical disinfection, and portable sanitizers. RoHS-compliant, halogen-free, and Vishay Green, the VLMU60CL..-280-125 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
