Vishay quartz-based ceramic UVC emitting diodes

New Yorker Electronics has added short wavelength ultraviolet (UVC) emitting diodes to its portfolio, with its release of the Vishay compact SMD device for sterilization, sanitation and purification applications.

Designed to replace mercury UVC lamps, the VLMU35CL00-280-120 delivers an extremely long lifetime in a 3.5mm by 3.5mm by 1.2mm surface-mount package with a quartz window that eliminates the need for an external lens.

The device offers an emission angle of ± 60°C and high radiant power to 3.2mW at 20 mA or 7.5mW at 50 mA. Built on AlGaN technology, the VLMU35CL00-280-120 features maximum forward voltage of 6.5V, a wavelength range of 265nm to 285nm, and forward current up to 70mA, compared to 30mA for typical competing parts.

The emitter diode’s specifications make it suitable 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.
