New Vishay Intertechnology Mid-Power Ultraviolet Emitting Diode With Quartz Window Delivers Extremely Long Lifetime
Ceramic Device Features Radiant Power to 18 mW in Compact 3.5 mm by 3.5 mm by 1.2 mm SMD Package
MALVERN, Pa. — Feb. 7, 2019 — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a ceramic mid power ultraviolet (UVC) emitting diode for sterilization, sanitation, and purification applications. Featuring a quartz window, the Vishay Semiconductors 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 released today 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.
