01 May 2020

New Yorker Electronics has added to its portfolio of short wavelength ultraviolet (UVC) emitting diodes with its release of the new Vishay Intertechnology compact surface mount device for sterilization, sanitation and Source: New Yorker ElectronicsSource: New Yorker Electronicspurification applications. Designed to replace mercury UVC lamps, the Vishay Semiconductors VLMU35CL00-280-120 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 released by New Yorker Electronics offers an emission angle of ±60° C and high radiant power to 3.2 mW at 20 mA or 7.5 mW at 50 mA. Built on aluminum gallium nitride technology, the Vishay VLMU35CL00-280-120 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 ideal for water and air purification, physical surface sterilization, medical disinfection and portable sanitizers. 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.
