Diode Principle Application

(Summary description)Rectifier diodes are mainly used in rectifier circuits, that is, to convert alternating current into pulsating direct current.

Information
1. Rectification
 
Rectifier diodes are mainly used in rectifier circuits, that is, to convert alternating current into pulsating direct current. The rectifier diodes are all surface junction types, so the junction capacitance is large, so that the operating frequency is low, generally below 3kHZ.
 
2. Switch
 
Under the action of forward voltage, the resistance of the diode is very small, and it is in an on state, which is equivalent to an on switch; under the action of reverse voltage, the resistance is very large, and it is in an off state, like an off switch. Using the switching characteristics of diodes, various logic circuits can be formed.
 
3. Limiting
 
After the diode is turned on, its forward voltage drop remains basically unchanged (0.7V for silicon tubes and 0.3V for germanium tubes). Using this feature, as a limiting element in the circuit, the signal amplitude can be limited within a certain range.
 
4. Freewheeling
 
It plays the role of freewheeling in the inductance of switching power supply and inductive loads such as relays.
 
5. Detection
 
The main function of the detection diode is to detect the low frequency signal in the high frequency signal. Their structure is of the point contact type. The junction capacitance is small and the operating frequency is high, and it is generally made of germanium material.
 
6. Damping
 
Damping diodes are mostly used in high-frequency voltage circuits, which can withstand higher reverse breakdown voltage and larger peak current. They are generally used in TV circuits. Commonly used damping diodes are 2CN1, 2CN2, BSBS44, etc.
 
7. Display
 
For VCD, DVD, calculator and other monitors.
 
8. Voltage stabilization
 
This kind of tube is made of the reverse breakdown characteristics of the diode, and the voltage across it remains basically unchanged in the circuit, which plays a role in stabilizing the voltage. Commonly used voltage regulators are 2CW55, 2CW56 and so on.
 
9. Trigger
 
Trigger diode, also known as bidirectional trigger diode (DIAC), is a three-layer structure and a symmetrical two-terminal semiconductor device. It is often used to trigger triacs; it is used for overvoltage protection in circuits.
