SMD LEDs
17 August 2010
Vishay’s red, amber, yellow, and white power SMD LEDs measure 3.5mm x 3.5mm x 1.2mm.
The VLMx51 series comes in the compact PLCC2 Plus package and offers high luminous flux and very low junction-to-ambient thermal resistance for a range of lighting applications.
Built on high-efficiency InGan and AllnGaP-on-silicon technology, the VLMR51, VLMK51, VLMY51, and VLMW51 devices offer high luminous flux from 8.5 lm to 30.6 lm and luminous intensity from 2,850mcd to 9,750mcd. The LEDs provide extremely low junction-to-ambient thermal resistance down to 100K/W and power dissipation up to 738mW, which in turn enables high drive currents up to 200mA.
These values, when combined with the devices' compact outline, make the VLMx51 series suitable for internal and exterior automotive lighting, signal and symbol illumination, decorative lighting, architectural lighting, backlighting, marker lights, traffic lights, and all general lighting applications.
For automotive applications, the LEDs are automotive qualified AEC-Q101. The VLMx51 devices feature a 60° angle of half-intensity, a luminous flux ratio per packing unit of <1.6, and are categorised, per packing unit, for luminous flux and colour.
The LEDs are compliant to RoHS directive 2002/95/EC, in accordance to WEEE 2002/96/EC, and are compatible with IR-reflow soldering profiles according to J-STD-020. The devices are preconditioned according to JEDEC Level 2a, and offer an ESD-withstand voltage of up to 2 kV (HBM) according to JESD22-A114-B.
Samples and production quantities are available now with lead times of eight weeks for larger orders.
