The optoelectronics group of Vishay Intertechnology has introduced a new series of super red, red, amber, and yellow ultrabright LEDs in compact untinted surface-mount packages with dome lenses.
Using AllnGaP on silicon chip technology, the VLD.1535 series delivers high brightness with luminous intensity to 14000 mcd and an emission angle of ± 22 degrees without the need for an external lens.
With their high brightness and small 2.3 mm by 2.3 mm by 2.6 mm footprints, the LEDs are suitable for 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 are said to 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 colour-categorised per packing unit.
