1、 Diode

A diode is a semiconductor device and one of the most common devices in electronics. It is composed of p-type and n-type semiconductors and has unidirectional conductivity, which means it can only conduct under forward voltage and turn off under reverse voltage. There are many types of diodes, including ordinary diodes, BQ24040DSQR Schottky diodes, light-emitting diodes, etc.diode

1. Ordinary diode

Ordinary diodes, also known as rectifier diodes, are one of the most common types of diodes. Its main function is to convert alternating current into direct current, and it can also be used for signal detection, voltage stability, and other purposes. In general, the forward operating voltage of a regular diode is 0.6-0.7V, and the reverse breakdown voltage is around 50-100V.diode

2. Schottky diode

Schottky diode is a special type of diode composed of an n-type semiconductor and a metal. Schottky diodes have the characteristics of low forward voltage drop and fast recovery speed, and are commonly used in high-frequency circuits, high-speed switches, and other fields.diode
