Vishay Releases New VLMW611.. and VLMW621.. Series of Warm White Power SMD LEDs in CLCC-6 and CLCC-6 Flat Package With Industry’s Lowest Profile of 0.9 mm
Devices Utilize InGan Technology to Offer Luminous Intensity Range of 1800 mcd to 7100 mcd, and Low Resistance of 40 K/W and 50 K/W
MALVERN, Pa. — March 12, 2008 — Vishay Intertechnology, Inc. (NYSE: VSH) today released two new series of warm white power SMD LEDs that utilize InGan technology to offer low resistance and high optical power. The VLMW611.. series is offered in the CLCC-6 package, while the VLMW621.. series features the CLCC-6 flat package, which offers an industry-low height profile of 0.9 mm.
Among the most robust and light-efficient products on the market, the devices’ ceramic packages make them the ideal light source in applications where careful thermal management is essential. Their low thermal resistance allows these devices to handle the additional current drive needed for maximum light output while maintaining a long service life of up to 50,000 hours.
The new LEDs are optimized for backlighting and illumination in automotive and transport, consumer, and general applications. Typical end products include handheld mobile devices, such as mobile phones and PDAs; instrument panels; marker lights; advertising displays; household appliances, such as refrigerators, washers, and driers; and bicycle lamps.
All devices have a 140-mA forward current, with a 4.3-V maximum forward voltage and 650-mW power dissipation. They provide an optical efficiency of 24 lm/W and an ESD-withstand voltage up to 1 kV according to JESD22-A114-B.
The LEDs offer a 60° half-intensity angle, and are compatible with IR-reflow solder processes according to CECC 00802 and J-STD-020C. The devices are automotive qualified to AEC-Q101 and comply with RoHS 2002/95/EC and WEEE 2002/96/EC. Preconditioned according to JEDEC Level 4 standards, the CLCC-6 and CLCC6 flat packages are lead (Pb)-free and RoHS-compliant.
