Avago expands 3W LED emitter family for solid-state lighting applications

Avago Technologies, a 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.

Key Features
• 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
• High flux output and energy efficient
• Low thermal resistance to provide improved device reliability and extend operating life
• Direct heat transfer from metal slug to mother board
• Silicone encapsulation
• Compatible with reflow soldering processes
• Non-ESD sensitive (threshold > 16kV)
• Moisture sensitivity: MSL 2a
• Pb-Free and RoHS compliant

Pricing and Availability
Avago’s ASMT-Ax3x LEDs are priced at $2.90 each in 1,000 piece quantities. Samples and production quantities are available now through Avago’s direct sales channel and worldwide distribution partners.
