Vishay released two series of warm white power SMD LEDs. The VLMW611 series is offered in the CLCC-6 package, while the VLMW621 series features the CLCC-6 flat package, which offers an height profile of 0.9mm. The devices utilize InGan Technology to offer luminous intensity range of 1800mcd to 7100mcd. Their 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 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 24lm/W and an ESD-withstand voltage up to 1kV 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.
