With their high brightness and small 2.3 mm by 2.3 mm by 2.6 mm footprints, the LEDs released today are the perfect choice for reliable performance in a wide range of applications, including traffic signals and signs, interior and exterior lighting, and indicators and backlighting for audio and video equipment, LCD switches, and illuminated advertising.
 
Available in gullwing and reverse gullwing versions, the devices offer high luminous flux and incorporate larger chip sizes to withstand drive currents up to 70 mA. The LEDs withstand ESD voltages up to 2 kV in accordance with JESD22-A114-B, and are luminous- and color-categorized per packing unit.
 
RoHS-compliant, halogen-free, and Vishay Green, VLD.1535..series LEDs are compatible with reflow soldering processes per J-STD-020 and preconditioned according to JEDEC Level 2a.
