Vishay has released a series of high-intensity amber and yellow power SMD LEDs in the CLCC-2 flat ceramic package with driving currents up to 400 mA. The robust and light-efficient VLMK82.. and VLMY82.. devices offer low thermal resistance of 20 K/W and high optical power from 5600 mcd to 14 000 mcd for thermal-sensitive applications.
With a low profile of only 0,75 mm, the flat ceramic package allows the additional current drive for a maximum light output while maintaining a high service life of up to 50 000 hours, making them ideal light sources in space-limited applications where thermal management is a key consideration.
With excellent efficiencies in brightness, lifetime, and power savings in a compact package, the devices are optimised for backlighting and illumination in automotive and transport, consumer and general applications. Typical end products include retail and window displays, signage and graphics, household appliances, and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
Utilising AlInGaP technology, the amber LEDs offer optical power from 7100 mcd to 14000 mcd and a typical luminous flux of 28000 mlm. The yellow devices provide optical power from 5600 mcd to 11 200 mcd and a luminous flux of 26000 mlm. Both LEDs feature optical efficiency of 40 lm/W at 100mA, a luminous intensity ratio per package unit of IV max/IV min less than 1,6, and 60° half-intensity angle.
The new devices are compatible with IR-reflow solder processes, in accordance with CECC 00802 and J-STD-020C. Preconditioned according to JEDEC Level 4 standards, the CLCC-2 flat package is lead-free and RoHS-compliant. The LEDs are automotive qualified to AEC-Q101 and offer an ESD-withstand voltage up to 2 kV in accordance with JESD22-A114-B.
