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.
