Devices Provide Low Thermal Resistance Down to 40 k/W and High Optical Power From 2240 mcd to 5600 mcd for High-Volume Applications
MALVERN, Pa. — Sept. 19, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today released the industry’s first high-intensity white power SMD LEDs in the CLCC-6 and CLCC-6 flat ceramic packages to offer InGaN/TAG on sapphire technology for high optical power from 2240 mcd to 5600 mcd.
Designed to reduce costs in high-volume applications, the new VLMW63.. series features the CLCC-6 package and a low thermal resistance to 50 k/W, while the VLMW64.. series in the CLCC-6 flat package offers a low thermal resistance of 40 k/W and an ultra-low profile of 0.9 mm.
With compact footprints of 3.3 mm by 3.4 mm, the ceramic packages of the LEDs allow 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 devices are optimized for backlighting and illumination in automotive and transport, consumer, and general applications. Typical end products include flashes for cameras; emergency lighting; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
The LEDs offer a typical luminous flux of 11000 mlm and optical efficiency up to 30 lm/W. The devices feature a luminous intensity ratio per package unit of IV max/IV min ≤ 1.6, forward voltage up to 4.3 V, and 60° half-intensity angle.
The VLMW63.. and VLMW64.. 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-6 and CLCC-6 flat packages are lead (Pb)-free and RoHS-compliant. The devices are automotive qualified AEC-Q101 and offer an ESD-withstand voltage up to 2 kV in accordance with JESD22-A114-B.
Samples and production quantities of the new VLMW63.. and VLMW64.. high-intensity white power SMD LEDs are available now, with lead times of eight weeks for larger orders.
