Power SMD white LEDs

9 June 2010 Opto-Electronics

Vishay announced the release of new power surface-mount white LEDs in two binning versions. For a wider range of pin compatibility with similar devices, the VLMW321xx LEDs feature three anodes and one cathode, while the VLMW322xx LEDs offer three cathodes and one anode.

The devices feature a PLCC 4 package with a lead frame optimised to provide very low thermal resistance down to 300 kW and power dissipation up to 200 mW, which in turn enables high drive currents up to 50 mA for twice the brightness of Vishay’s high-intensity SMD LEDs in the PLCC 2 package. For automotive applications, the VLMW321xx and VLMW322xx LEDs are automotive qualified to AEC-Q101. Silicone casting provides for a long service life.

The high-intensity LEDs are intended for traffic signals and signs; interior and exterior lighting; automotive interior and exterior lighting; indicators and backlighting in household appliances, toys and games, and mobile phones; camera flashes; and general illumination for retail and window displays, emergency lighting and signs, and museums and showrooms.

Built on high-efficiency InGaN technology, the VLMW321xx and VLMW322xx devices provide a high luminous intensity of 1400 mcd to 3550 mcd, and luminous flux from 7000 mlm to 8900 mlm. The LEDs feature a 60° angle of half-intensity and a luminous intensity ratio per packing unit of less than 1,6, and are categorised, per packing unit, for luminous intensity and colour. The lead-free and RoHS-compliant devices are available in 8 mm tape and are compatible with IR-reflow, vapour phase and wave soldering processes according to CECC 00802 and J-STD-020, and preconditioning according to JEDEC Level 2a. The LEDs offer an ESD-withstand voltage up to 2 kV (HBM).
