Long-life ceramic / quartz-based UVC LED is only 3.5x3.5x1.2mm

July 18, 2019 //By Julien Happich
Vishay Intertechnology has added a compact SMD device to its portfolio of short wavelength ultraviolet (UVC) emitting diodes for sterilization, sanitation, and purification applications.

Designed to replace mercury UVC lamps, the VLMU35CL..-280-120 delivers an extremely long lifetime in a 3.5 x3.5x1.2mm surface-mount package with a quartz window that eliminates the need for an external lens. The device has an emission angle of ± 60° and high radiant power to 3.2mW at 20mA or 7.5mW at 50mA. Built on AlGaN technology, the UVC LED has a maximum forward voltage of 6.5V, a wavelength range of 265nm to 285nm, and forward current up to 70mA, compared to 30mA for typical competing parts. RoHS-compliant, halogen-free, and Vishay Green, the device is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
