Four diode bridge rectifier. In silicon diode the dark band indicates the cathode terminal and the other terminal is anode.

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

Types of diodes video. The anode and the cathode. Pin diodes this diode has intrinsic semiconductor sandwiched between p type and n type region. 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.
Zener diode used for voltage regulation. Today there are dozens of diode types that are used in all types of electrical and electronic circuits. Most diodes are constructed with semiconductor materials though some contain metal or pure elemental gas in the electrodes.
Like small signal diode large signal diode zener diode light emitting diode led constant current diodes. A diode is an electronic component that conducts electrical current in one direction and blocks current in the opposite direction. 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. In this lesson we explore the fundamental operation of a diode. Each diode contains two electrodes.
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. In this episode karen reviews p in junctions and talks about how they differ from other types of common diodes such as schottky diodes zener diodes leds light emitting diodes laser diodes. They are used as ohtodiodes and radio frequency switches.
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. In this video i try to explain about each and every types of diode which are available. Different types of diodes have different voltage requirements.
Doping does not occur in this type of diode and thereby the intrinsic semiconductor increases the width of the depletion region. This type of diode is commonly used for rectification or conversion of an ac signal to dc as shown below. Some of these are listed below.
Semiconductor diodes are the most common type of diode. We also look are some the various types of diodes such as the zener diode the schottky diode the light emitting diode and the.
