Avago Technologies is offering small, energy-efficient 3W high-power LEDs with high color rendering index (CRI) for use in a wide range of solid-state lighting applications.

With dimensions of 5mm x 4mm x 1.85mm thick, Avago's compact 3W ASMT-Jx33 is packaged in a 6-leaded SOP and capable of being driven to up to 700mA to provide high flux output performance. Additionally, this competitively priced compact LED emitter provides a wide viewing angle and features long life reliability.

The ASMT-Jx33 has a wide viewing angle of 140 to meet the needs of designers who require good color uniformity. This LED provides a high typical CRI of 80 for cool white and 90 for warm white. Avago's 3W emitter is a high performance LED designed to handle high thermal and high drive currents. By delivering a high flux output of 70 lumens at 350mA, this new 3W LED emitter is ideal for use in general lighting applications such as medical lighting, merchandise display lighting and museum lighting. Additionally, this LED features a maximum allowable junction temperature of 135C thus providing lighting designers with more design flexibility. In addition, this part offers a high 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. Moreover, this 3W LED is compatible with standard SMT reflow soldering processes which helps lower design cost.

The ASMT-Jx33 line is available in cool white, neutral white and warm white colors. The LEDs feature high maximum junction temperature and direct heat transfer from metal slug to mother board. The devices are compatible with reflow soldering processes and offer long operating life.

Avago's ASMT-Jx33 LEDs are priced at $2.50 each in 1,000-piece quantities. Samples and production quantities are available through Avago's direct sales channel and worldwide distribution partners.
