Vishay introduced a new ceramic / quartz-based UVC (short wavelength ultraviolet) emitting diode for sterilization, sanitation, and purification applications. Designed to replace mercury UVC lamps, the Vishay Semiconductors VLMU60CL..-280-125 delivers an extremely long lifetime in a 6 mm by 6 mm by 1.6 mm surface-mount package.
Comparable to devices in the PLCC2 package with emission angles of ±60°, the device released today 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.
The emitter diode’s specifications make it ideal for water and air purification, physical surface sterilization, 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.
