SMD Diode Bridge: A Comprehensive Industry Overview
Introduction to SMD Diode Bridge
The SMD diode bridge, also known as a surface mount diode bridge, is an essential component in the field of electronics. It is a compact, four-diode assembly that provides full-wave rectification of AC (alternating current) to DC (direct current). This article aims to provide a comprehensive overview of the SMD diode bridge industry, covering its history, applications, market trends, and future prospects.
History of SMD Diode Bridge
The concept of the diode bridge dates back to the early 20th century, when the first rectifiers were developed.
