New Vishay Intertechnology UVC Emitting Diodes in Ceramic / Quartz-Based Package Offer Higher Radiant Power at a Lower Cost Than Previous-Generation Solutions
September 14 2022 - 11:00AM
Vishay Intertechnology, Inc. (NYSE: VSH) today introduced two new
UVC (short wavelength ultraviolet) emitting diodes in a ceramic /
quartz-based package for sterilization in medical, industrial, and
consumer applications. Compared to previous-generation solutions,
the Vishay Semiconductors VLMU35CR40-275-120 and VLMU35CR41-275-120
deliver higher radiant power at a lower cost while offering higher
disinfection efficiency and a longer service life.
The devices released today feature high typical radiant power of
37 mW at 250 mA, which in terms of mW/$ performance is 30 %
higher than lower power emitter diodes and 12x better than
previous-generation solutions. In addition, the VLMU35CR41-275-120
provides a minimum radiant power of 30 mW at 250 mA, which is
the same as the closest competing device at 350 mA.
The emitter diodes offer a wavelength range of 265 nm to 280 nm,
with a typical wavelength of 274 nm. Not only is this suitable for
direct disinfection of surfaces, air, and static water, but
compared to 280 nm solutions, the VLMU35CR40-275-120 and
VLMU35CR41-275-120 deliver 20 % higher sterilization efficiency.
Available in a compact, thermally optimized surface-mount 3.45 mm
by 3.45 mm by 1.7 mm package with a ceramic substrate and quartz
window, the devices ensure a long service life of 27 000 hours
at 250 mA and 25 °C.
Built on AlGaN technology, the VLMU35CR40-275-120 and
VLMU35CR41-275-120 are designed to replace low pressure UVC mercury
tubes, especially in compact designs where small components are
required. Typical end products will include sterilization devices
for ear buds, toothbrushes, water bottles, refrigerators, air
purifiers, door handles, medical instruments, coffee machines,
ATMs, toilet seats, vacuum cleaners, and more.
The devices feature DC forward current up to 300 mA, forward
voltage down to 5.2 V, and an emission angle of ± 60°.
RoHS-compliant, halogen-free, and Vishay Green, the
VLMU35CR40-275-120 and VLMU35CR41-275-120 are compatible with
reflow soldering processes and feature a Moisture Sensitivity Level
of 3 in accordance with J-STD-020.
Samples and production quantities of the new UVC emitting diodes
are available now, with lead times of eight to 16 weeks.
