Top 10 Diode Suppliers in China 2025

Introduction to Diodes

A diode is a two - terminal electronic component that conducts current primarily in one direction (asymmetric conductance). It has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. Diodes are fundamental building blocks in electronic circuits, used in a wide range of applications such as rectification (converting alternating current to direct current), signal demodulation, voltage regulation, and protection against reverse current. They come in various types, including rectifier diodes, Zener diodes, Schottky diodes, and light - emitting diodes (LEDs). In China, the diode industry has witnessed significant growth in recent years, with many suppliers emerging to meet the domestic and international demand.
