Types of diodes.

There are many types of diodes, which can be divided into germanium diodes (GE tubes) and silicon diodes (Si tubes) according to the semiconductor materials used. According to its different uses, it can be divided into detection diodes, rectifier diodes, voltage regulator diodes, switching diodes, etc. According to the die structure, it can be divided into point contact diode, surface contact diode and planar diode.

The point-contact diode is pressed on the surface of a smooth semiconductor wafer with a very thin metal wire, and a pulse current is passed to make one end of the contact wire and the wafer firmly sintered together to form a "p-n junction". Because it is a point contact, only a small current (no more than a few tens of milliampes) is allowed to pass through, and it is suitable for high-frequency and low-current circuits, such as radio detection.

The large area of the "p-n" junction of the surface contact diode allows a large current (a few amps to tens of amps) to pass through, and is mainly used in "rectification" circuits that convert alternating current into direct current.

Planar diode is a special silicon diode, which can not only pass large currents, but also has stable and reliable performance, and is mostly used in switching, pulse and high-frequency circuits.

There are many types of diodes, all have unidirectional conductive performance, can not be said to be substituted for each other, only in line with the frequency characteristics of the switching diode and the switching loss of small high-frequency diodes can replace the switching diodes, the specific use of the parameters should be carefully compared with the substitution, the listed diodes, only part of the detection diodes can be replaced.

What are the models of diodes? That's a tricky question. There are many factors that determine the size of the diode.

It is necessary to distinguish according to factors such as material power and so on. In addition, those who are familiar with it know that there are many types of diodes! Common diode models include rectifier diodes; switching diodes; Detection diodes and more!

If you want to determine the specific diode model, you can consult those electronic component companies, generally have a very good understanding of these diode models, mastery!

There are many types of diodes, but the most common ones are only a few, such as rectifier diodes; switching diodes; Detection diodes; Zener Zener Zener Diodes; Reference Zener Diode; light-emitting diodes; varactor diodes; Transient Voltage Suppression Diodes (TVS); Schottky diodes, etc.! If you want to know more about diodes, you can go to ryshoo!

Diodes are a large category of components, containing a huge number of models.

For example, there are nearly 10,000 models of TVS diodes.

A diode is a semiconductor device with a p-n junction. It is composed of a p-type semiconductor and an n-type semiconductor inside the hood, which leads out the corresponding electrode leads at both ends of the pn junction, and the tube shell is sealed to make a diode.

There are many types of diodes, which can be divided into rectifier diodes, voltage regulator diodes, light-emitting diodes, photosensitive diodes, detection diodes, varactor diodes, bidirectional trigger diodes, etc.

There are many types of diodes, which can be divided into rectifier diodes, voltage regulator diodes, light-emitting diodes, photosensitive diodes, sleepy detector diodes, varactor diodes, bidirectional trigger diodes, etc.

There are many types of diodes, and the specific types are: TVS transient (variable) voltage suppression diodes, ESD electrostatic diodes, voltage regulator (Zener) pre-spring call diodes, Schottky diodes, rectifier diodes, switching diodes, fast recovery diodes, ultra-fast recovery diodes, trigger diodes, high-efficiency diodes, constant current diodes, avalanche diodes, power diodes, modulation diodes, mixing diodes, high-frequency diodes, high-voltage diodes, detector diodes, damping diodes, varactor diodes, Amplification diodes, trigger diodes, light-emitting diodes, laser diodes, photosensitive diodes, color-sensitive diodes, magneto-sensitive diodes, thermal diodes, microwave diodes, infrared emitting diodes, dual-base diodes, rotating diodes, fiber-coupled diodes, pin diodes, TVP tubes, diode chips, other diodes, etc.

Diode.

The VZMIN of the 2CW51 regulator tube is and the VZMAX is.

When the working current of the 2CW7C regulator tube is 5mA, the RZ is 18; When the working current is 10mA, the rz is 8; At 20mA, Rz is 2; >20mA is basically the same value.

If the VZ of the 2CW51 regulator tube is 3V and the IZM is 20mA, then the PZ of the tube is the temperature coefficient of the regulator tube is +, that is, the voltage regulator value will increase for every 1°C increase in temperature.

When the vr=1V of the 2CW58 regulator tube, IR=; At vr=6V, IR=10UA.

The diode model is generally directly represented by letters or numbers on it, if it is a patch, it is necessary to distinguish the circuit diagram, and the chip components are now used more, many of which cannot be distinguished by the naked eye, and a detailed circuit diagram is needed to check.
