Power SMD white LEDs from Vishay targeting elctronic devices lighting apps

Vishay has introduced the VLMW321xx and LMW322xx, a two new power surface-mount white LEDs, which are suitable for lighting applications such as traffic signals and signs, interior and exterior lighting, automotive interior and exterior lighting, indicators and backlighting in household appliances, toys and games, camera flashes, and mobile phones.

The VLMW321xx LEDs feature three anodes and one cathode, and the VLMW322xx LEDs offer three cathodes and one anode.

The key features of the VLMW321xx, VLMW322xx LEDs are,

High efficient INGaN technology
Long life time, due to silicone casting
Available in 8 mm tape
Luminous intensity ratio per packing unit IVmax./IVmin. = 1.6
ESD-withstand voltage: up to 2 kV (HBM) according to JESD22-A114-B
Preconditioning: according to JEDEC level 2a
Compatible with IR-reflow, vapor phase and wave soldering processes according to CECC 00802 and J-STD-020
AEC-Q101 qualified
Compliant to RoHS directive 2002/95/EC and in accordance to WEEE 2002/96/EC

The VLMW321xx and VLMW322xx LEDs provide low thermal resistance down to 300 K/W 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. These devices also 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 categorized, per packing unit, for luminous intensity and color.

Package: PLCC-4 package
