Abstract

The invention provides a planar rectification diode. The planar rectification diode comprises an anode leading wire (1), a cathode leading wire (2), a silicon dioxide protective layer (3) and a positive-negative (PN) junction (4), wherein the anode leading wire (1) is connected with the silicon dioxide protective layer (3), the silicon dioxide protective layer (3) is connected with the PN junction (4), and an adhesive layer (5) and a copper-nickel alloy layer (6) are sequentially coated outside the anode leading wire (1) and the cathode leading wire (2). The planar rectification diode provided by the invention has the following technical effects: 1) a pin is difficult to be bent or broken; and 2) the pin is difficult to be inserted deeply during embedment, and welding instability is prevented.

Description

technical field [0001] The invention relates to a planar rectifier diode and belongs to the technical field of semiconductors. Background technique [0002] Diode is one of the most commonly used electronic components. Its biggest characteristic is unidirectional conduction, that is, current can only flow from one direction of the diode. The function of the diode is a rectifier circuit, a detection circuit, a voltage stabilization circuit, and various modulation circuits. , are mainly composed of diodes, and their principles are very simple. It is precisely because of the invention of diodes and other components that we have the birth of our colorful electronic information world. [0003] The existing diodes have the following disadvantages: [0004] 1) The pins are easily bent or broken; [0005] 2) The pins are easy to be inserted too deep when inlaying, resulting in unstable welding. [0006] These shortcomings have seriously affected the service life of the diode...
