Long-life ceramic / quartz-based UVC emitting diode comes in compact SMD package


VISHAY SEMICONDUCTORS VLMU35CL-280-120, compact, short wavelength ultraviolet (UVC) emitting SMD diodes for sterilization, sanitation and purification applications, is designed to replace mercury UVC lamps. Device delivers an extremely long lifetime in a 3.5mm by 3.5mm by 1.2mm surface-mount package with a quartz window that eliminates the need for an external lens. Device provides an emission angle of ± 60° and high radiant power to 3.2mW at 20mA or 7.5mW at 50mA. Built on AlGaN technology, device delivers 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.
