Datasheet

Expanding its offering of mid-power UV LEDs in the 365nm wavelength range, Vishay Intertechnology announces the VLMU1610-365-135 with a silicone lens in a compact 1.6x1.6x1.4mm surface-mount package. The VLMU1610-365-135 is designed to provide a reliable, energy-saving replacement for mercury lamps and delivers an exceptionally long lifetime for medical, industrial and printing applications.

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

Built on InGaN (indium gallium nitride) technology, the device released today features typical radiant power of 18mW at 20mA and 50mW at 60mA in a wavelength range between 362.5nm and 370nm. The VLMU1610-365-135 offers an emission angle of 135°. The LED's specifications make it ideal 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 of the VLMU1610-365-135 UV LED are available now, with lead times of six to eight weeks.
