Vishay Intertechnology Inc. has debuted a series of ultra-bright LEDs that according to the company enables the development of smaller end products, more flexibility in design and enhanced applications. The VLMx1300 series uses the ChipLED technology and has 130 wide viewing angle.

The LEDs in the VLMx1300 series come in what the company said is the smallest SMD 0603 package and are mounted on PCBs measuring 1.6 x 0.8 x 0.55mm. Available colors include super red, soft orange, yellow, yellow green, true green, blue and white. Using ultra-bright AllnGaP and InGaN technologies (depending on color), the color LEDs have a luminous intensity as high as 450mcd at 20mA forward current and maximum forward voltage of 3.8V. Blue is available with a protection diode that provides ESD immunity up to 8kV. The white LED has a maximum luminous intensity of 180mcd at 5mA forward current of and maximum forward voltage of 3.15V.

VLMx1300

The VLMx1300 series from Vishay touts 130 viewing angle.

The VLMx1300 ChipLED series can be used in keypads, navigation systems, cellular phone displays, displays for industrial control systems, miniaturized color effects and traffic displays. The white version works well in backlighting for telephone and fax, audio and video equipment, office equipment, indoor and outdoor message boards, and flat backlight for LCDs, switches and symbols.

The devices are available in 8mm tape on a 7in diameter reel grouped by luminous intensity and wavelength to ensure an even appearance in end products, noted Vishay. They are compatible with IR reflow soldering and compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC. VLMx1300 LEDs are Pb-free and are geared for Pb-free soldering.

Samples and production quantities of the ChipLEDs are available with lead times of eight weeks for larger orders.
