: 03 October, 2003 (New Product) |
|
|
A new series of low-current, surface-mount LEDs based on the ultra-bright AllnGaP technology was launched today by Vishay Intertechnology, Inc. |
|
At a forward current of just 2 mA, super red, orange, and yellow LEDs in the new Vishay Semiconductors TLMx300x series provide exceptional brightness in low-power applications including backlighting and indicators in automotive, telecommunications, office equipment, entertainment systems, and a variety of battery-driven equipment.
The TLMS3000 and TLMS3001 super red LEDs feature a dominant wavelength of 630 nm and typical luminous intensities from 2.5 mcd to 12.5 mcd. Available with a dominant wavelength of 606 nm, the new TLMO3000 and TLMO3001 orange LEDs feature typical luminous intensities from 5.0 mcd to 20 mcd. With a dominant wavelength of 587 nm, the TLMY3000 and TLMY3001 yellow LEDs offer typical luminous intensities from 4.0 mcd to 20 mcd.
The new devices are embedded in a small white EIA- and ICE-standard package measuring 2.8 mm by 3.0 mm with a height profile of 1.65 mm. The P-LCC-2 package consists of a lead frame embedded in a white thermoplast, with an interior reflector filled with clear epoxy. All six devices feature a 60° angle of half intensity and a non-diffused lens that facilitates coupling to light pipes. Each LED is luminous intensity and color categorized for each packing unit, and a luminous intensity ratio of 2.0 or less per packing unit ensures even lighting.
The TLMx300x series is rated for a 125 °C junction temperature, a thermal resistance junction of 400 K/W, and an operating temperature range of -40 °C to +100 °C. The new LEDs offer ESD-withstand voltage of up to 1 kV. Automatic assembly is simplified with CECC compatibility for infrared, vapor phase, and wave soldering methods.
Provided in 8-mm tape form, samples and production quantities of the new TLMx300x SMD LEDs are available now, with lead times of six weeks for larger orders. |
