Intro:
What is a diode? Diode is a double ended electronic device that allows current to flow in only one direction in a circuit. Today it is also used as a diode for electrically inducing and radiating, emitting and vibration sensing electronic switches. is used A solar cell is also an attractive source of electricity A type of photosensitive diode.
Diode:
Diode allows current to flow in a specific direction. Prevents the flow of current in its opposite direction. like this. The tendency to drift in one direction is called rectification. It is made from AC current to DC current and gedo The first step in the signal gateway.
Application of Diode:
Works on reverse voltage protection. Works on high voltage protection. Used in clipping circuits. Acts as a switch. Acts as a rectifier. Acts as modulation. Also used in logic circuits. Used in wave shaping circuits. Used in clamping circuits. It also acts as a detector.
How diode works:
Diodes are basically made of P type and N types semiconductors. P Type semiconductors contain very few free electrons and many holes. For this reason, in P Type semiconductor, the hole is called the majority charge carrier and the free electron is called the minority charge carrier. On the other hand, N type semiconductor has many electrons and very few holes, so in this type of semiconductor, electrons are called majority charge carriers and holes are called minority charge carriers All types.
Two modes of operation of diodes based on voltage:
Forward Bias: In PN junction the positive source is connected to the P terminal and the negative source is connected to the N terminal, so the voltage crosses the potential barrier and current flows through the junction, it is called forward bias. Remains Reverse Bias: The negative end of the supply voltage at the P level of the PN junction and the positive end of the supply voltage at the N level are connected to form the reverse bias of the junction.
Diode Samples:
All Types Of Diode:
Zener diode, Photo diode, Gunn diode, Tunnel diode, Pin diode, Schottky diode, Light emitting diode, Backward diode, Baritt diode.
Zener Diode:
Zener Diode which does not forward current but reverse current. A zener diode has more distortion than voltage. Zener Diode which does not forward current but reverse current. A zener diode has more distortion than voltage.
What is zener diode:
Zener diode in electronics circuit is a type of constant and invariable DC voltage supplier which is invariable in the output even if the input voltage of the circuit varies slightly and the same voltage is always available. Such fixed or unchanging DC voltage is called stabilized DC or regulator voltage in English.
What is Zener Diode Called:
Zener diode is a device in an electronic circuit that produces a precisely regulated voltage according to the output of the device without any variation in the DC voltage at the output. A zener diode gives the same rated output voltage as a regulated IC.
Use of Zener Diode:
A specific output voltage is obtained by Zener diode. Zener diodes of the same voltage as the output are required are used in the electronics circuit. Zener diodes of various voltages are available in the market. Above which the output voltage and amperes are mentioned and the output voltage and amperes have to be set in the circuit. If the output voltage is not written, it should be purchased after knowing the seller's work.
Pin Diode:
Pin diode is used for very fast operation. It can work in gigahertz range.
Schottky diode:
Schottky diode is generally used in computer processors for power savings i.e. to drop the voltage. That is why Schottky diode is used.
Light Emitting Diode:
A diode works in forward. These diodes are widely used in audio systems, monitor backlights, digital meters.
A photo diode:
Photo-diode refers to a type of diode that works by reflecting light. Namely, if light rays fall on this diode, voltage can flow through it. No voltage can pass through the blind car diode. When light falls on it, the leakage current changes. How much leakage current will change from it depends on the light falling on it.
What is photo diode called:
A photo-diode is a type of diode that operates when light rays fall on it and an electrical voltage flows through it. In short, a junction diode when placed in a short circuit is called a photo diode. Photo diodes like Zener diodes are reverse biased. The value of which changes depending on the yield of light.
Do the work of Tamod::
Photodiodes are used in a variety of electronic devices. For example, this mode is widely used in various devices to catch thieves, computer devices, fire or fire alarms, light presence detection devices, etc.
Gunn Diode:
A Gunn diode, also known as a transferred electron device, is a form of diode, a two-terminal semiconductor electronic component, with negative differential resistance, used in high-frequency electronics. It is based on the "Gunn effect" discovered by physicist JB Gunn in 1962.
Gunn diodes are mainly used to generate microwaves in applications such as radars, electronic oscillators, radar speed guns, microwave relay data link transmitters, and automatic door openers.
