Avago Technologies Expands Series of 3-Watt High Power LED Emitters for Solid-state Lighting Applications

New 3-Watt LEDs are a Drop-in Replacement for One of the Most Common Footprints in the SSL Industry

LIGHT + BUILDING, FRANKFURT, GERMANY, April 14, 2010 - Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced the expansion of its series of compact, energy efficient 3-Watt (3W) high power LEDs for solid-state lighting (SSL) applications. Avago’s ASMT-Ax3x Power LED emitter has a footprint that is one of the most commonly used throughout the SSL industry. Typical applications include architectural lighting, retail display lighting and decorative lighting.

Avago’s ASMT-Ax3x provides superior light output uniformity with a wide viewing angle of 140 degrees which is suitable for backlighting of advertising displays, channel letters and contour lighting. The ASMT-Ax3x delivers high flux output up to 113 lumens (lm) at 350 mA driving current and features a maximum allowable junction temperature of 135 degrees-C to provide lighting designers with more design flexibility. Moreover, this LED has a high Electrostatic Discharge (ESD resistance of 16kV which makes this LED insensitive to ESD. As a result, special ESD protection equipment is not required to handle the part during installation. Additionally, this part is compatible to IR reflow soldering process.

The ASMT-Ax3x is encapsulated in a heat and UV resistant silicone compound and also features a low thermal resistance of 10 degree-C per Watt due to its superior heat dissipation capability. In addition, the electrically neutral heat pad allows arrays to be connected on a common heat sink – thus simplifying thermal design.


  • Available in cool white, neutral white, warm white, royal blue, blue, amber, red-orange and red colors
  • Drop-in replacement for 3W Luxeon platform LEDs
