It functions as a two terminal current limiter. Because of this electrical property diodes are used to convert alternating current electrical energy into direct current electrical energy.

The key function of a diode is to control the direction of the flow of current.

Functions of a diode. What are the functions of a zener diode. Rectifier diodes these are the most common with its function described above. Let us understand different types of diodes with their applications and functions.

Some of them are changing ac current to dc current by removing part of the signal. However unlike a resistor a diode does not behave linearly with respect to the applied voltage as the diode has an exponential current voltage. Current passing through a diode can only go one way which is called forward biased.

The structure of such diode is shown in the figure 1 and figure 2 along with its characteristics. The p n diode consists of p n junction with one connection to p side eg. They function as electrical switches and are useful in surge protectors because they can prevent voltage spikes.

Rectifier diodes are electronic devices that allow electrical current to flow in one direction only. There are several types of diodes. The constant current diode symbol is shown below.

The function of the diode is regulating the voltage at a particular current. The maximum voltage rating specifies how much reverse voltage a diode can. Diodes are used in numerous ways.

In this capacity they are known as rectifiers. In this jfet acts as current limiter to achieve high output impedance. For voltage regulation zener diodes are.

A pn junction diode is one of the simplest semiconductor devices around and which has the characteristic of passing current in only one direction only. The main function of a diode is to block the current in one direction and allow current to flow in the other direction. The diodes are able to maintain constant output voltages throughout current changes in.

Anode and another connection to n side eg. Current flowing through the diode is called forward current. The most common function of a diode is to allow an electric current to pass in one direction called the diodes forward direction while blocking it in the opposite direction the reverse direction.
