High-performance rectifier diode

Technical Field

Background

A rectifier diode is a semiconductor device used to convert alternating current to direct current. The most important characteristic of a diode is one-way conductivity. In the circuit, current can only flow in from the anode and flow out from the cathode of the diode. Typically it comprises a PN junction having two terminals, a positive and a negative terminal. The carriers in the P region are holes, the carriers in the N region are electrons, and a certain barrier is formed between the P region and the N region. When the voltage applied to the P region is positive with respect to the N region, the potential barrier is lowered, and storage carriers are generated near both sides of the potential barrier, so that a large current can pass through the storage carriers, and the P region is in a forward conduction state with a low voltage drop. When a reverse voltage is applied, the potential barrier is increased, a high reverse voltage can be borne, and a small reverse current flows, which is called a reverse blocking state. The rectifier diode has a significant unidirectional conductivity. The rectifier diode can be made of semiconductor germanium or silicon. The silicon rectifier diode has high breakdown voltage, small reverse leakage current and good high-temperature performance. High-voltage high-power rectifier diodes are usually made of high-purity monocrystalline silicon. The junction area of such devices is large and can pass large currents, but the operating frequency is not high, typically below a few tens of kilohertz. The rectifier diode is mainly used for various low-frequency half-wave rectifier circuits, and is connected into a rectifier bridge for use if full-wave rectification is required; a plurality of connecting contacts are arranged on the outer side of the existing rectifier diode, and the contacts are likely to break when the rectifier diode is collided during carrying, so that the use is influenced.
