Abstract

Provided in the invention is a point contact type rectifier diode comprising an anode lead wire (1), a cathode lead wire (2), a PN junction (3), an N type germanium slice (4), a bracket (5), a metal whisker (6) and a shell (7). The anode lead wire (1) and the N type germanium slice (4) are connected to the two ends of the metal whisker (6); the N type germanium slice (4) and the bracket (5) are connected to the two ends of the PN junction (3); the cathode lead wire (2) and the bracket (5) are connected; and the PN junction (3), the N type germanium slice (4), the bracket (5), and the metal whisker (6) are arranged in the shell (7). Adhesive layers and albata layers coat the outsides of the anode lead wire (1) and the cathode lead wire (2) successively. According to the invention, the point contact type rectifier diode has the following technical effects: firstly, pins are not easy to fold or break; and secondly, when the pins are embedded, deep insertion can be prevented and thus instable welding can be avoided.

Description

technical field [0001] The invention relates to a point contact type rectifier diode, which 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 in one direction of the diode. The function of the diode includes rectifier circuit, detection circuit, voltage regulator 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 our current colorful electronic information world was born. [0003] The existing diodes have the following shortcomings: [0004] 1) The pins are easily bent or broken; [0005] 2) The pins are easy to be inserted too deeply when inlaid, resulting in unstable soldering. [0006] These deficiencies seriously affect the life of the diode. ...
