Diodes: Diodes are semiconductor devices that only allow one direction of electricity to flow. There are several types of diodes available depending on the application:
Types of Diode:
1. Large signal Diode: The PN junction layer in large-signal diodes is quite thick. These diodes are most commonly seen in battery charging equipment such as inverters. These diodes' excellent current and voltage capability make them ideal for suppressing high peak voltages in electrical equipment.
2. Light-emitting Diode: From mobile phones to massive advertising billboards, light-emitting diodes (LEDs) are used in a wide range of applications. It's a semiconductor-based light source. When current is passed through the LED, the electrons recombine with the holes, resulting in the emission of light.
3. Small signal Diode: Radios and televisions both employ small signal diodes. The doping substance determines the diode's properties.
4. Zener Diode: A Zener diode is a semiconductor device with a high doping content that is designed to work in the opposite direction. For regulating voltage across modest loads, a Zener diode is employed as a Shunt voltage regulator. Over-voltage protection and clipping circuits also make use of them.
5. Schottky Diode: Barrier diode, hot-electron diode, hot carrier diode, and majority carrier diode are all terms used to describe a Schottky diode. A Schottky diode is a unipolar device in which current is solely conducted due to electron mobility.
6. Varactor Diode: A varactor diode is a type of diode in which the internal capacitance fluctuates depending on the reverse voltage. It is a voltage-dependent semiconductor device that always operates in reverse bias.
