Patent ID: 7679090

Claim:
An SMD diode packaging structure, comprising: a plastic housing having a concave function area located in an interior of one surface of the plastic housing and a concave notch located in an interior of a second surface of the plastic housing, the concave notch being misaligned in relation to the concave function area, and a size of the concave notch being smaller than a size of the concave function area; a plurality of metal holders fastened in the plastic housing, wherein each metal holder has a base portion located in the plastic housing and a connecting pin portion extending to an outside of the plastic housing from the base portion, a top surface of the base portion is exposed to the function area, and a bottom surface of the base portion is exposed to the concave notch; at least one LED chip located on a top surface of one of the base portions and received inside the concave function area, wherein the LED chip is connected with a top surface of the base portion via a first conductive wire; a first sealing compound combining with the function area of the plastic housing for covering the LED chip; an anti-ESD chip connected with a bottom surface of another base portion that is opposite to the base portion with the LED chip and received inside the concave notch, wherein the anti-ESD chip is connected with a bottom surface of the base portion with the LED chip via a second conductive wire; and a second sealing compound combining with the notch for covering the anti-ESD chip.
