What is a rectifier diode, its characteristics, classifications, and common parameters 1

In electronics, rectification is the process of converting alternating current (AC) into direct current (DC). In practical circuits, rectifier circuits are required to convert AC into DC to power electronic devices. The rectifier diode ISO124P is a component used for converting AC to DC, functioning as a semiconductor device typically made of silicon or silicon carbide. A rectifier diode is a bidirectional conduction device that allows current to pass under forward voltage while blocking it under reverse voltage.diode

The characteristics of rectifier diodes

The characteristics of a rectifier diode primarily include the forward voltage drop and the reverse breakdown voltage.

The forward voltage drop refers to the voltage drop generated inside a rectifier diode under forward voltage, typically ranging from 0.5V to 0.7V. This occurs because when the PN junction of the rectifier diode is forward-biased, electrons and holes recombine, releasing energy and causing a reduction in the internal voltage of the rectifier diode.diode

The reverse breakdown voltage refers to the phenomenon where a rectifier diode experiences breakdown and generates a large current under reverse voltage. The reverse breakdown voltage is the maximum voltage tolerance of a rectifier diode, typically ranging from several hundred volts to several thousand volts.diode

Classification of Rectifier Diodes

Rectifier diodes can be classified based on their structure, operating mode, and maximum rated current.diode
