New Mid-Power Ultraviolet Emitting Diode with Quartz Window Delivers Extremely Long Lifetime

Posted Feb 11, 2019 by Vishay Intertechnology

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

Designed to replace mercury UVC lamps, the device offers an emission angle of ± 60° and radiant power to 18 mW at 100 mA without the need for an external lens. Built on 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.

Samples of the new UVC emitting diode are available now. Production quantities are available with lead times of four weeks. 

Vishay Intertechnology is one of the world's largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
