Vishay - Power SMD White LEDs in Thermally Enhanced PLCC-4 Package Feature Two Binning Versions, High Luminous Intensity to 3550 mcd, and Thermal Resistance Down to 300 K/W

The devices released today feature a PLCC-4 package with a lead frame optimized to provide very 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. For automotive applications, the VLMW321xx and VLMW322xx LEDs are automotive qualified 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 categorized, per packing unit, for luminous intensity and color.

The lead (Pb)-free and RoHS-compliant devices are available in 8-mm tape and are compatible with IR-reflow, vapor 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) according to JESD22-A114-B.
