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

23-07-2019 | Vishay | Subs & Systems

Vishay Intertechnology adds to its portfolio of short-wavelength ultraviolet (UVC) emitting diodes a compact new SMD device for sterilisation, sanitation, and purification applications. Intended to replace mercury UVC lamps, the VLMU35CL..-280-120 provides a very long lifetime in a 3.5mm x 3.5mm x 1.2mm surface-mount package with a quartz window that removes the requirement for an external lens.


The device released today offers an emission angle of ±60-degrees and high radiant power to 3.2mW at 20mA or 7.5mW at 50mA. Built on AlGaN technology, the device features maximum forward voltage of 6.5V, a wavelength range of 265nm to 28 nm, and forward current up to 70mA, compared to 30mA for typical competing parts.


The emitter diode's specifications make it excellent for water and air purification, physical surface sterilisation, medical disinfection, and portable sanitisers. RoHS-compliant, halogen-free, and Vishay Green, the device is compatible with reflow soldering processes and offers a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
