Vishay Intertechnology Unveils Long-Life Ceramic / Quartz-Based UVC Emitting Diode
Device in SMT Package from Vishay Intertechnology Features Radiant Power to 3.8 mW at 20 mA and ± 62.5° Emission Angle
Vishay Intertechnology unveils 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 touts to deliver 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 recent device released 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, theVLMU60CL..-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.
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.
Applications
The emitter diode’s specifications make it ideal for water and air purification, physical surface sterilization, medical disinfection, and portable sanitizers.
Availability
Samples of the new UVC emitting diode are available now. Production quantities will be available in Q1 2018 with lead times of eight weeks.
