What Are The Main Parameters of Lujing diode?
The technical specifications used to indicate the performance of a diode and its application range are called diode parameters. Different types of diodes have different characteristic parameters. In this paper, we mainly introduce the main parameters of the Lujing diode.
The main parameters of Lu Jing diode are the following five:
1, the maximum rectification current IF
The maximum rectified current IF is the maximum forward average current that the diode is allowed to pass through for a long period of time. The value is related to the PN junction area and the external heat dissipation conditions. As the current passes through the tube, the die heats up and the temperature rises. When the temperature exceeds the allowable limit (approximately 141 for a silicon tube and about 90 for a germanium tube), the die is overheated and damaged. Therefore, in the specified heat dissipation conditions, the diode should not exceed the maximum rectified current of the diode.
2, the highest reverse voltage Udrm
When the reverse voltage applied across the diode reaches a certain value, it will breakdown the tube and lose its unidirectional conductivity. In order to ensure the use of safety, the maximum reverse voltage is specified. For example, 1N4001 diode reverse voltage is 50V, 1N4007 reverse voltage is 1000V.
3, reverse current Idrm
Reverse current refers to the reverse current flowing through the diode at normal temperature (25℃) and maximum reverse voltage. The smaller the reverse current, the better the unidirectional conductivity of the tube. It is worth noting that the reverse current has a close relationship with the temperature. When the temperature rises by 10℃, the reverse current doubles.
4, dynamic resistance Rd
The ratio of the change in voltage near the static operating point Q of the diode characteristic curve to the amount of change in the corresponding current.
5, the maximum operating frequency Fm
Fm is the upper limit frequency of diode operation. Because the diode is the same as the PN junction, its junction capacitance consists of a barrier capacitance. Therefore, the value of Fm mainly depends on the size of the PN junction capacitance. If more than this value. Unidirectional conductivity will be affected.
The above are the main parameters of Lujing diodes. Beginners and practitioners engaged in the electronics industry, must have a profound understanding in order to be able to do a good job in their daily work.

The Role and Working Principle of the Diode
Among the diode electronic components, a device having two electrodes allows current to flow only in a single direction, and many uses the function of rectification. The varactor is used as an electronically tunable capacitor. The current directionality of most diodes is often referred to as the “Rectifying“ function. The most common function of a diode is to allow only current to pass in a single direction (called forward bias) and reverse in reverse (called reverse bias).

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.
Power Diode Problem Introduction
What is the reverse leakage current of the diode? When the diode is turned off in the reverse direction, it is not a perfectly ideal cutoff. When subjected to back pressure, some tiny current leaks from the cathode to the anode. This current is usually small, and the higher the back pressure, the larger the leakage current, and the higher the temperature, the larger the leakage current. Large leakage currents can cause large losses, especially in high voltage applications.
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.
