Tricolor LEDs slim front panels
By Bill Schweber -- EDN, March 3, 2005
A new surface-mount RGB LED from BivarOpto, the optoelectronics division of Bivar, measures just 0.6 mm (0.024 in.) thick, making it a good fit with thin enclosures, such as handheld devices, screen backlights, and games. The SMTC0606, in a standard 1.5×1.6-mm package, is encapsulated in epoxy with a lens that appears “water clear” when off (Picture). Each of the three LED dice (one comprised of AlGaInP and two of InGaN/SiC) is individually addressable, so your system can fully control the color mixing and appearance. Maximum forward drive current is 125 mA. Color output is at 635, 520, and 465 nm for red, green, and blue, respectively. The lead-free device sells for $1.45 (OEM quantities).
