What is the Role of Zener Diode?
The main characteristics of the diode is unidirectional conductivity, that is, under the action of the forward voltage, the on-resistance is very small; while the reverse voltage effect on-resistance is very large or infinity. Because of the diode has the above characteristics, the circuit often used in the rectifier circuit, then the role of Zener diode is what? Let's take a look.
Zener diode voltage regulator principle: Zener diode is the reverse voltage breakdown plus the breakdown, the voltage at both ends of the basic remain unchanged. The rectifier diode is damaged after the reverse breakdown. In this way, when the voltage regulator connected to the circuit, if the power supply voltage fluctuations, or other causes of the circuit voltage changes at each point, the voltage across the load will remain essentially unchanged. Zener diode used to regulate or in the series circuit as a reference voltage.
Rectifier diodes and Zener diodes are PN semiconductor devices, the difference is that the rectifier diode is used in the unidirectional conductivity Zener diode is the use of its reverse characteristics, the reverse connection in the circuit.
The main purpose of the regulator is to stabilize the voltage. In the request of accuracy is not high, the current range is not large, the regulator can be selected and the need for the most close to the regulator in parallel with the load directly. Regulated, steady current power supply system as a general reference power, but also in the integrated op amp as a DC level shift.
The above is the role of Zener diode, as the name suggests is a stable voltage.

What Are the Main Characteristics of Transient Suppression Diodes?
The transient suppression diode, abbreviated as TVS, is a high-efficiency protection device in the form of a diode. This article mainly introduces the main parameters of the TVS diode.The VS tube is divided into one-way and two-way. The characteristics of the one-way TVS tube are similar to those of the Zener diode. The characteristics of the two-way TVS tube are equivalent to two Zener diodes connected in reverse series.
Talking about the Selection and Use Conditions of Zener Diode
The Zener diode is a special diode that operates in a reverse breakdown state, making the voltage across the tube essentially constant. When selecting a Zener diode, it should be considered according to the specific electronic circuit. A simple parallel regulated power supply, the output voltage is the stable voltage of the Zener diode. The regulated power supply of the transistor radio can be selected with a 2CW54 type voltage regulator tube, and its stable voltage can reach 6.5V.

Diode Classification
The basic principle is to block the reverse voltage with the already formed Schottky on the contact surface of the metal (for example, lead) and the semiconductor (N-type silicon wafer). There is a fundamental difference between the Schottky and PN junction rectification principles. Its pressure resistance is only about 40V. Its speciality is: the switching speed is very fast: the reverse recovery time trr is particularly short. Therefore, a switching diode and a low-voltage high-current rectifier diode can be fabricated.

Silicon Rectifier Diode Characteristics and Working Principle
Rectifier diodes are mainly used for various low-frequency half-wave rectifier circuits. If full-wave rectification is required, they must be used as rectifier bridges. This article mainly introduces the characteristics and working principle of silicon rectifier diodes.The rectifying diode uses the unidirectional conductive characteristic of the PN junction to convert the alternating current into pulsed direct current. Rectifier diodes have large leakage currents, and most are diode-packaged diodes.

The Forward and Reverse Resistors of 1N4007 Silicon Rectifier Diode
The 1N4007 is a plastic packaged general-purpose silicon rectifier diode in the form of DO-41. Widely used in various AC to DC rectifier circuit. Also used for bridge rectifier circuit. The 1n4007 utilizes the unidirectional conductivity of the diodes to convert alternately alternating currents into a single direction pulsed direct current. This article describes the 1N4007 diode forward resistance and reverse resistance.
Schottky Diode Action
Due to schottky dioderobust structure, fast response and low clutter, Schottky diodes are widely used in high frequency circuits. In recent years, it has also been used in low-voltage, high-current power circuits and AC-DC converter systems.
