A new high-brightness, tricolor LED optimised for interior automotive lighting, RGB displays, and backlighting has been introduced by Vishay Technology. Featuring separate red, green, and blue LED chips inside the compact 3.5 mm by 2.8 mm by 1.45 mm PLCC-6 surface-mount package, the Vishay Semiconductors VLMRGB611w. enables individual control of each chip, making it possible to realise every colour within the colour room defined by the gamut triangle area inside the CIE 1931 colour space through colour mixing.

With its wide colour range, the LED released today is ideal for custom “welcome illumination” in next-generation automobiles; large-format, full-colour message and video display boards; backlighting in consumer devices and appliances such as PDAs, televisions, ovens, and microwaves; and a wide range of accent and decorative lighting.

For these applications, the device utilises high-brightness AllnGaP and InGaN technologies to deliver luminous intensity to 1800 mcd at 20 mA and features a ±60° angle of half intensity.

Providing high reliability, the Automotive Grade VLMRGB6112.offers a wide temperature range from -40 °C to +110 °C, excellent corrosion robustness and sulphur resistance (H2S), and a UV-stable, diffused silicone casting compound for a long lifetime.

The LED is AEC-Q101-qualified, offers a Moisture Sensitivity Level (MSL) of 2, and withstands ESD voltages up to 2 kV in accordance with JESD22-A114-B. Compatible with IR reflow soldering, the device is RoHS-compliant, halogen-free, and Vishay Green.
