SMD diode holding structure and package thereof

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.
