Devices Combine Low Thermal Resistance Down to 25 K/W and High Optical Power From 5600 mcd to 14000 mcd for High-Volume Applications
MALVERN, Pa. — Dec. 17, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today released the industry’s first series of high-intensity white power SMD LEDs in the CLCC-2 flat ceramic package to offer InGaN/TAG on sapphire technology. Designed to reduce costs in high-volume applications, the VLMW84.. devices offer low thermal resistance of 25 K/W and high optical power from 5600 mcd to 14000 mcd.
With an ultra-low profile of only 0.75 mm, the CLCC-2 flat ceramic package of the VLMW84.. LEDs allows the additional current drive for a maximum light output while maintaining a high service life of up to 50,000 hours, making them ideal light sources in space-limited applications where thermal management is a key consideration.
The new devices are optimized for display backlighting and illumination in automotive and transport, consumer, and general applications. An eco-friendly alternative to CCFL display backlighting, the Vishay CLCC-2 LED offers excellent efficiencies in brightness, lifetime, and power savings in a compact package (3.3 mm x 3.4 mm). Typical end products include flashes for cameras; emergency lighting and signs; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
The LEDs offer a typical luminous flux of 27000 mlm and optical efficiency of 40 lm/W at 100 mA. The devices feature a luminous intensity ratio per package unit of IV max/IV min ≤ 1.6, forward voltage up to 5 V, and 60° half-intensity angle.
The VLMW84.. LEDs are compatible with IR-reflow solder processes, in accordance with CECC 00802 and J-STD-020C. Preconditioned according to JEDEC Level 4 standards, the CLCC-2 flat package is lead (Pb)-free and RoHS-compliant. The devices are automotive qualified AEC-Q101 and offer an ESD-withstand voltage up to 1 kV in accordance with JESD22-A114-B.
Samples and production quantities of the new VLMW84.. high-intensity white power SMD LEDs are available now, with lead times of eight weeks for larger orders.
