Malvern, Pa. Vishay Intertechnology, Inc. has released two series of warm white power SMD LEDs that use InGan technology to offer low resistance and high optical power. The VLMW611.. series is offered in the CLCC-6 package, while the VLMW621.. series is housed in the CLCC-6 flat package, which offers an industry-low height profile of 0.9 mm.
All devices provide 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. Thanks to the use of InGan technology, the devices offer a luminous intensity range of 1800 mcd to 7100 mcd and low resistance of 40 K/W and 50 K/W.
Vishay said the devices' ceramic packages make them suitable as a 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, bicycle lamps as well as household appliances such as refrigerators, washers, and driers.
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.
Pricing: $0.90/piece for U.S. delivery.
Availability: Samples and production quantities are available now, with lead times of six weeks for larger orders.
