Ceramic Device Features Radiant Power to 18 mW in Compact 3.5 mm by 3.5 mm by 1.2 mm SMD Package

Vishay Intertechnology, Inc introduced a ceramic mid-power ultraviolet (UVC) emitting diode for sterilization, sanitation, and purification applications. Featuring a quartz window, the Vishay Semiconductors VLMU35CM..-280-120 delivers an extremely long lifetime in a compact 3.5 mm by 3.5 mm by 1.2 mm surface-mount package.

Designed to replace mercury UVC lamps, the device released today offers an emission angle of ± 60° and radiant power to 18 mW at 100 mA without the need for an external lens. Built on AlGaN technology, the VLMU35CM..-280-120 features forward current up to 150 mA, forward voltage down to 4 V, and a wavelength range of 270 nm to 290 nm.

The emitter diode’s specifications make it ideal for water and air purification, physical surface sterilization, medical disinfection, and portable sanitizers. RoHS-compliant, halogen-free, and Vishay Green, the VLMU35CM..-280-120 is compatible with reflow soldering processes and features a Moisture Sensitivity Level of 3 in accordance with J-STD-020.

Features

  • Ceramic SMT package with quartz window
  • Dimension (L x W x H) in mm: 3.5 x 3.5 x 1.2
  • Forward current: up to 150 mA
