Vishay Intertechnology announces mid-power ultraviolet emitting diode with quartz window

08 February 2019

Vishay Intertechnology Inc. has introduced a ceramic, mid-power, ultraviolet (UVC)-emitting diode for sterilization, sanitation and purification applications. Featuring a quartz window, the Vishay Semiconductor VLMU35CM..-280-120 delivers a long lifetime in a compact 3.5 mm x 3.5 mm x 1.2 mm surface-mount package.

Designed to replace mercury UVC lamps, the device offers an emission angle of ± 60° C and radiant power to 18 mW at 100 mA, without the need for an external lens. Built on aluminum gallium nitride (AlGaN) technology, the VLMU35CM..-280-120 features forward current up to 150 mA, forward voltage down to 4 V and a wavelength range of 270 nm to 290 nm.

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 VLMU35CM..-280-120 is compatible with reflow soldering processes and features a moisture sensitivity level of 3 in accordance with J-STD-020.
