Types de diode pdf. The semiconductor diode is widely used in many areas of electronics today. Although they use the same basic structure of an area of p type material meeting an area of n type material there are many different types of diode that are available in todays electronics scene. A number of specific types of diodes are manufactured for specific applications in this fast developing world.

In silicon diode the dark band indicates the cathode terminal and the other terminal is anode. Piv is the peak inverse voltage of the diode forward bias occurs when the p type block is connected to the positive terminal of the battery and the n type is connected to the negative terminal of the battery as shown below. Semiconductor diodes are the most common type of diode.

A diodes i v characteristic is shown in figure 6 below. Some of the more common special purpose diodes are i zener diode ii light emitting diode led iii photo diode iv tunnel diode v varactor diode and vi shockley diode. V slightly different than jds negative resistance veractor junction cap.

The different kinds each have their own specialized uses. Some diodes such as zener diodes function as voltage regulators because when reverse bias is fed it above a certain point the diode maintains a constant voltage across its terminals. Many different types of diodes today are in use in electronics.

Generally diodes are used as reverse polarity protector and transient protector. For silicon diodes the forward voltage is 07v and for germanium it is 03v. Although in the real world diodes can not achieve zero or infinite resistance.

A diode is a two terminal device having two active electrodes between which it allows the transfer of current in one direction only. But rectification is not all that a diode can do. D0 03 v.

A diode is effectively like a valve for an electrical circuit. Some of the types may overlap but the various definitions may benefit to narrow the field down and offer an overview of the different diode types. Najmabadi ece65 winter 2012.

Diodes are known for their unidirectional current property wherein the electric current is allowed to flow in. Different types of diodes have different voltage requirements. Schottky barrier diode large.

Most of the diodes are made from semiconductors like si silicon but sometimes ge germanium is also usedit is sometimes beneficial to summarize the different types of diodes are existing. Useful as a reference voltage in many circuits. On silicon tunnel i vs.

Instead a diode will have negligible resistance in one direction to allow current flow and a very high resistance in the reverse direction to prevent current flow.
