New series of red, amber, yellow and white power SMD LEDs from Vishay

Date: 20/07/2010

Vishay has released the VLMx51 series new red, amber, yellow, and white power SMD LEDs in the compact PLCC2 Plus package. These LEDs offer high luminous flux and low junction-to-ambient thermal resistance and is suggested for a wide range of lighting applications.

These LEDs are built using InGan and AllnGaP silicon technology. The VLMR51, VLMK51, VLMY51, and VLMW51devices offer high luminous flux from 8.5 lm to 30.6 lm and luminous intensity from 2,850 mcd to 9,750 mcd. The LEDs provide low junction-to-ambient thermal resistance down to 100 K/W and power dissipation up to 738 mW, which in turn enables high drive currents up to 200 mA. These devices come in a compact 3.5-mm by 3.5-mm by 1.2-mm package outline. The VLMx51 series is suggested for internal and exterior automotive lighting, signal and symbol illumination, decorative lighting, architectural lighting, backlighting, marker lights, traffic lights, and all general lighting applications. These LEDs are automotive qualified AEC-Q101. The VLMx51 devices feature a 60° angle of half-intensity, a luminous flux ratio per packing unit of less than 1.6, and are categorized, per packing unit, for luminous flux and color.

These LEDs are complaint 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 up to 2 kV (HBM) according to JESD22-A114-B.
