Vishay's TELUX LED

Vishay Intertechnology Inc. unveiled six new TELUX series clear, non-diffused red LEDs featuring one of the industry's brightest AllnGaP on GaAs (OMA) technologies. According to the company, these new LEDs are constructed with a special oval lens that reduces the number and cost of LEDs required in automotive and other lighting applications.

Designed for applications requiring utmost luminous flux, the new TELUX LEDs provide broad illumination that enables more efficient lighting for traffic signals and signs. These devices can also serve as replacements for small incandescent lamps.

Available in an industry-standard 7.62mm2 package, the LEDs feature a 90K/W heat dissipation, which in turn allows for a high operating temperature range of -40C to 110C. Because all packaging units are binned for luminous flux, forward voltage and color, they provide a very homogenous appearance when used together in the same lighting system, said Vishay.

Luminous intensity ratings for the new devices are >3,000-, >3,500- and >4.000mlm, available with a 25 x 68 or 40 x 90 angle of half intensity. All six red LEDs meet SAE and ECE color requirements for automotive applications, and are rated for ESD resistivity of 2kV (HBM) according to MIL STD 883D, method 3015.7.

The TELUX LEDs have been packed in tubes for automatic insertion. Each device is Pb-free and compliant with RoHS 2002/95/EC and WEEE 2002/96/EC.

Samples and production quantities of the new red TLWR9420, TLWR9421, TLWR9422, TLWR9520, TLWR9521 and TLWR9522 TELUX LEDs are already available, with lead times of four weeks.
