Types Of Diodes Symbols

The symbol used for a semiconductor diode in a circuit diagram specifies the type of diode. These are mainly P-N junction diodes Photosensitive diodes Zener diodes Schottky diodes Varactor diodes.

A diode is effectively like a valve for an electrical circuit.

Types of diodes symbols. The main types of diodes are the following. The arrow in the diode symbol represents the direction of conventional current flow when the diode conducts. This is the basic diode formed with the interaction of p-type and n-type materials.

In this article lets cover only the three main types of diodes they are the Rectifier Diode Zener Diode and Schottky Diode. A vacuum tube diode is a vacuum tube with two electrodes a plate anode and heated cathode. Semiconductor diodes are the most common type of diode.

A diode is effectively like a valve for an electrical circuit. This type of diode made from of a small junction between an N-type semiconductor and a metal. Besides the above mentioned types of diodes the other diodes are PIN diode point contact diode signal diode step recovery diode tunnel diode and gold doped diodes.

Schottky diode varactor diode and a number of others fall into this category. Tunnel rectifier diode. In this tutorial we will learn about Different Types of Diodes.

Photosensitive diodes include LEDs Photodiodes and Photovoltaic cells. There are many different types of diode and some use circuit symbols that are slightly modified from the basic diode symbol to indicate their function. It has no P-N junction like normal diodesDue to which it has very low forward voltage drop and fast switching because there is no capacitive junction P-N junction.

Likewise when the cathode voltage is more positive than the anode the diode is said to be reverse-biased. Todays most commonly used diode is semiconductor diodeIn our previous articles we explain basic theory of semiconductors P-n junction diode and P-n junction diode characteristics etc. Either in the forward direction or in the reverse direction.

There are alternative symbols for some types of diodes though the differences are minor. P-N Junction Diode Small Signal Diode Rectifier Diode Schottky Diode Super Barrier Diodes Light Emitting Diode LED Photodiode Laser Diode Tunnel Diode Zener Diode Backward Diode Avalanche Diode Transient Voltage Suppression TVS Diode Gold Doped Diode Constant Current Diode Step Recovery Diode Peltier Or Thermal Diode Vacuum Diode Varactor Diode Gunn Diode PIN Diode Silicon Controlled Rectifier SCR Shockley Diode Point Contact Diode. These diodes are dependent on the type of diodes that have the characteristics of turning-off fast based on their operation.

Instead a diode will have negligible resistance in one direction to allow current flow and very high resistance in the reverse direction to prevent current flow. Diode rectifier diode Generic symbol Info. Including p-n diode Schottky diode Shockley diode Constant-current diode Zener diode Light-emitting diode Photodiode Tunnel diode Varactor Laser diode PIN diode Gunn diode and so on 1 P-N Junction Diode.

Although in the real world diodes can not achieve zero or infinite resistance. Symbol Description Symbol Description. There are several types of diodes and those are available for use in electronics design namely.

In the direction of conventional current flow. The symbol used to represent a particular type of diode in a circuit diagram conveys the general electrical function to the reader. Left - Anode Right - Cathode.

Snap diode SRD Step Recovery Diode Info. A Backward diode BARRITT diode Gunn Diode Laser diode Light emitting diodes Gold doped diodes crystal diode PN Junction Shockley diode Step recovery diode Tunnel diode Varactor diode and a Zener diode. The diode is called forward-assisted when running in this direction.

Tunnel diode Info. Surface mount devices or leaded Diodes come in all shapes and sizes. Semiconductor diode is the most common type of diode.

The picture terminal and symbol of all diodes are tabulated below Diode Type. A semiconductor diode the most common type today is a crystalline piece of semiconductor material with a pn junction connected to two electrical terminals. Symbol of Step Recovery Diode Hence the various types of diodes along with there applications are discussed above.

Diode is an electronic device conduct current in one direction ie. Diode schematic symbols of electronic circuit - Diode LED Zener diode Schottky diode photodiode. These include Small Signal Diodes Zener Diodes Light Emitting Diodes Schottky Diodes Tunnel Diodes Avalanche Diodes etc.

Here we are going to explain about Diodes and its types. Pin diode Info. Diode rectifier diode Generic symbol.

These diodes only begin to conduct electricity if a certain threshold voltage is present in the forward direction ie. These are of different types and transfers the electric current based on the properties and specifications of that particular diode. This will be a brief note on different types of diodes with basic functionality and its circuit symbol.

The triangle in the symbols points to the forward direction ie. Diode rectifier diode Zener diode Generic symbol Info. The type of diode to transfer electric current depends on the type and amount of transmission as well as on specific applications.
