The Applications of YFW General-Purpose Rectifier Diodes Introduction

1. Introduction

YFW, a renowned semiconductor company, manufactures a variety of high - quality general - purpose rectifier diodes. These diodes play a fundamental role in numerous electronic circuits, leveraging their unique electrical properties to perform essential functions. General - purpose rectifier diodes are two - terminal semiconductor devices that allow current to flow in one direction (forward - bias) while blocking it in the opposite direction (reverse - bias), which is crucial for converting alternating current (AC) to direct current (DC), among other applications.

2. Working Principle of General - Purpose rectifier diodes

A general - purpose rectifier diode is based on the p - n junction principle. When a positive voltage is applied to the p - type region (anode) and a negative voltage to the n - type region (cathode), the diode is in forward - bias. In this state, majority carriers (holes in the p - type and electrons in the n - type) are pushed towards the junction, reducing the width of the depletion region. As a result, current can flow through the diode with relatively low resistance.

Conversely, when a negative voltage is applied to the anode and a positive voltage to the cathode (reverse - bias), the majority carriers are pulled away from the junction, widening the depletion region. This creates a high - resistance barrier, and only a very small reverse - saturation current (due to minority carriers) can flow through the diode. YFW's general - purpose rectifier diodes are designed to optimize this basic principle, ensuring reliable operation under various electrical conditions.
