Ceramic/quartz-based UVC emitting diode replaces mercury UVC lamps
The VLMU60CL..-280-125 ceramic/quartz-based UVC (short wavelength ultraviolet) emitting diode features a radiant power to3.8mW at 20m and is claimed to deliver an “exceptionally” long lifetime.
Vishay Intertechnology offers the surface mount device for sterilisation, sanitation, and purification applications. Designed to replace mercury UVC lamps, the Vishay Semiconductors VLMU60CL..-280-125 is supplied in a 6.0 x 6.0 x1.6mm package.
Comparable to devices in the PLCC2 package with emission angles of ± 60 degrees, the diode offers an emission angle of ± 62.5 degree and high radiant power to 3.8mW at 20 mA without the need for an external lens.
Built on AlGaN technology, the VLMU60CL..-280-125 features forward current to 40mA, forward voltage down to 4.4V, and a wavelength range of 270 to 290nm.
RoHS-compliant and halogen-free, the VLMU60CL..-280-125 is compatible with reflow soldering processes and features a moisture sensitivity level of 3 in accordance with J-STD-020.
Samples of the VLMU60CL..-280-125 UVC emitting diode are available now. Production quantities will be available in Q1 2018 with lead times of eight weeks.
Vishay Intertechnology claims to be one of the world’s largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). The components it produces 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.
