What is a switching diode? The basic structure, characteristics, working principle, types, operating procedures, common problems, and development history of switching diodes 1

Switching diode is an M95040-WMN6TP electronic component used to control the flow of current. It has fast switching speed and small switching losses, can operate at high frequencies, and is widely used in power supplies, communications, computers, and various electronic devices.

1、 Basic structure:

Switching diode are composed of two semiconductor materials, one is a P-type semiconductor and the other is an N-type semiconductor. Among them, impurities in P-type semiconductors contain positive charges called holes, while impurities in N-type semiconductors contain negative charges called electrons. Two semiconductor materials are combined together through a PN junction to form the basic structure of a switching diode.

2、 Characteristics:

1. Fast switching speed: The switching speed of the switching diode is very fast, capable of completing switching operations in nanoseconds.

2. Low switching loss: Due to the absence of an emitter in the switching diode, its switching loss is relatively small, which can effectively reduce energy consumption.

3. High frequency operation: Switching diodes can operate at high frequencies and are suitable for controlling high-frequency circuits.

4. High reliability: Switching diodes have a long service life and high reliability.
