Description

Technical Field

[0001] The utility model relates to the technical field of diodes, in particular to a diode with high reliability. Background Art

[0002] The diode is an electronic device made of semiconductor materials. It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode is turned on, and when a reverse voltage is applied to the anode and cathode, the diode is cut off. Therefore, the conduction and cutoff of the diode are equivalent to the on and off of the switch. The diode has unidirectional conductivity. When it is turned on, the current flows from the anode through the tube to the cathode. The diode is one of the earliest semiconductor devices and is widely used. Especially in various electronic circuits, diodes and components such as resistors, capacitors, inductors, etc. are reasonably connected to form circuits with different functions, which can realize multiple functions such as rectification of alternating current, detection of modulated signals, limiting and clamping, and stabilization of power supply voltage. Publication No. CN219778869U discloses a diode, including a diode chip, the diode chip is covered with a plastic shell, the two ends of the plastic shell have arc chamfers, the anode end of the diode chip is connected to an anode lead, and the cathode end of the diode chip is connected to a cathode lead. Beneficial effects: The device structure of the present application is simple, and the arc chamfer is set, so that the insulation distance, space, and heat dissipation can be improved, and it is not easy to discharge between adjacent plastic shells, saving layout space. Although the product can improve the insulation distance, space, and heat dissipation, it is easy to break between the wire and the shell. When the diode is broken, it cannot be used normally. If the wire needs to be connected, it needs to be connected by welding, which reduces the reliability of the diode and has poor practicality, and needs to be improved. Utility Model Content
