Electrostatic discharge transistor

Abstract

The invention discloses an electrostatic discharge transistor which comprises a body. Pins are arranged at the bottom of the body, the body comprises a protective layer and a core layer, the core layer is located on the outer surface of the protective layer, and the protective layer comprises a first anti-corrosion layer, a second anti-corrosion layer, an anti-aging layer and an insulating layer.The first anti-corrosion layer is located on the outer surface of the second anti-corrosion layer, and the second anti-corrosion layer is located on the outer surface of the anti-aging layer. The first anti-corrosion layer has good mechanical property, heat resistance, wear resistance, chemical resistance and self-lubricating property, so that the service life of the body is prolonged; the secondanti-corrosion layer is stable in chemical property, and protection can be continued when the first anti-corrosion layer is damaged, so that the service life of the body is further prolonged, and theinsulating layer can prevent electric leakage. The anti-aging layer can prevent the insulating layer from aging and being damaged, and the problem that the service life of an existing electrostatic discharge transistor is shorter due to the fact that the anti-corrosion effect of the existing electrostatic discharge transistor is poor, is solved.

Description

Technical field [0001] The present invention relates to the technical field of transistors, in particular to an electrostatic discharge transistor. Background technique [0002] Transistor is a solid semiconductor device (including diodes, triodes, field effect transistors, thyristors, etc., sometimes referred to as bipolar devices), with multiple functions such as detection, rectification, amplification, switching, voltage stabilization and signal modulation. A variable current switch that can control the output current based on the input voltage. The ESD transistor is a type of transistor, but the existing ESD transistor has poor corrosion resistance, resulting in a shorter service life. For this reason, we propose a An electrostatic discharge transistor. Summary of the invention [0003] The purpose of the present invention is to provide an electrostatic discharge transistor, which has the advantage of good corrosion resistance, and solves the problem of poor corrosion resista...
