Vishay Intertechnology Inc. claims the industry's first series of high-intensity white power SMD LEDs in the CLCC-2 flat ceramic package. The VLMW82 devices offer low thermal resistance of 20 K/W and high optical power from 9000mcd to 18000mcd for thermal-sensitive applications.

With an ultralow profile of only 0.75mm, the CLCC-2 flat ceramic package of the VLMW82 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 (3.3mm x 3.4mm). Typical products include flashes for cameras; retail and window displays; emergency lighting and signs; household appliances; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.

Utilizing InGaN technology, the LEDs offer a typical luminous flux of 35000mlm and optical efficiency of 40lm/W at 100mA. The devices feature a luminous intensity ratio per package unit of IV max/IV min <1.6, forward voltage up to 4.3V, and 60 half-intensity angle.

The VLMW82 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 of the new VLMW82 series of high-intensity white power SMD LEDs are available now.
