Vishay Unveils Compact Long-Life UVC LED

News

SMD AlGaN device features forward current up to 70 mA, compared to 30 mA for typical competing parts

Vishay Intertechnology is adding to its portfolio of short wavelength ultraviolet (UVC) emitting diodes with a compact new SMD device for sterilisation, sanitation, and purification applications.

Designed to replace mercury UVC lamps, the Vishay Semiconductors VLMU35CL..-280-120 delivers an extremely long lifetime in a 3.5 mm by 3.5 mm by 1.2 mm surface-mount package with a quartz window that eliminates the need for an external lens.

The device offers an emission angle of ± 60° and high radiant power to 3.2 mW at 20 mA or 7.5 mW at 50 mA. Built on AlGaN technology, the VLMU35CL..-280-12 features maximum forward voltage of 6.5 V, a wavelength range of 265 nm to 285 nm, and forward current up to 70 mA, compared to 30 mA for typical competing parts.

The emitter diode's specifications make it suitable for water and air purification, physical surface sterilisation, medical disinfection, and portable sanitisers. RoHS-compliant, halogen-free, and Vishay Green, the VLMU35CL..-280-120 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.
