What is a rectifier diode, its characteristics, classifications, and common parameters 2

1. Structural Classification

Rectifier diodes can be classified into conventional rectifier diodes and Schottky diodes based on their structure. Conventional rectifier diodes consist of a PN junction formed by P-type and N-type semiconductors, while Schottky diodes are composed of a PN junction formed by a metal and N-type semiconductor.diode

2. Classification of Working Methods

Rectifier diodes can be classified into single-phase rectifier diodes and three-phase rectifier diodes based on their operation mode. Single-phase rectifier diodes are suitable for single-phase AC power supplies, while three-phase rectifier diodes are suitable for three-phase AC power supplies.

3. Maximum Rated Current Classification

Rectifier diodes can be classified into small-signal rectifier diodes and high-power rectifier diodes based on their maximum rated current. Small-signal rectifier diodes are suitable for circuits with low voltage and small current, while high-power rectifier diodes are suitable for circuits with high voltage and large current.diode

Common Parameters

Common parameters of rectifier diodes include rated voltage, maximum operating voltage, maximum rated current, reverse leakage current, and reverse breakdown voltage.diode

Rated voltage

The rated voltage refers to the maximum rated voltage of a rectifier diode under forward bias, typically ranging from 0.5V to 0.7V.diode
