Vishay launches mid-power 365nm UV LED delivering long lifetime in compact 1.6mm package

Vishay Intertechnology Inc of Malvern, PA, USA has expanded its offering of mid-power UV LEDs in the 365nm wavelength range with a new device featuring a silicone lens in a compact 1.6mm by 1.6mm by 1.4mm surface-mount package. Designed to provide a reliable, energy-saving replacement for mercury lamps, the Vishay Semiconductors VLMU1610-365-135 delivers long lifetime for medical, industrial and printing applications.

The silicone lens enables extremely long lifetimes of up to 25,000hr compared with the typical mercury lamp lifetime of 10,000hr. The environmentally friendly UV LED is free of heavy metals and provides increased reliability through its shock resistance and immunity to degradation from frequent on/off switching. While mercury lamps require complex drive circuits and need 2-15 minutes to warm up, the VLMU1610-365-135 allows the use of simple low-voltage circuitry and requires no warm-up period.

Fabricated from indium gallium nitride (InGaN) technology, the new LED features typical radiant power of 18mW at 20mA and 50mW at 60mA in a wavelength range of 362.5-370nm. The VLMU1610-365-135 has an emission angle of 135°.

The LED's specifications make it suitable for UV curing in nail salon, dental, and poster printing applications; blood and counterfeit money detection; and photocatalytic purification.

RoHS-compliant, halogen-free and Vishay Green, the VLMU1610-365-135 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.

Samples and production quantities are available now, with lead times of 6-8 weeks.
