Vishay Announces New UVC LED

News

AlGaN device features radiant power to 3.8 mW at 20 mA and ± 62.5 degree emission angle

Vishay Intertechnology has introduced a new ceramic / quartz-based UVC (short wavelength ultraviolet) LED for sterilistion, sanitation, and purification applications. Designed to replace mercury UVC lamps, the VVLMU60CL..-280-125 is said to deliver a 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 degrees, the device offers an emission angle of ± 62.5 degrees and high radiant power to 3.8 mW at 20 mA without the need for an external lens, according to Vishay.

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 suitable for water and air purification, physical surface sterilisation, medical disinfection, and portable sanitisers. The LED is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.

Samples of the new UVC LEDs are available now. Production quantities will be available in Q1 2018 with lead times of eight weeks.
