What are the two types of diodes commonly used in electronics?

The choice of standard diodes and Zener diodes represents two fundamental types of diodes that serve important roles in electronic circuits. Standard diodes, also known as regular or rectifying diodes, primarily conduct current in one direction and are commonly used for rectification processes, allowing alternating current (AC) to be converted into direct current (DC).

Zener diodes, on the other hand, are designed to undergo breakdown at a specific reverse voltage, allowing them to regulate voltage in circuits. They are frequently used in voltage regulation applications, where maintaining a constant output voltage is necessary, regardless of changes in input voltage or load conditions.

This combination of diodes covers essential functionalities: standard diodes for current rectification and Zener diodes for voltage regulation, making them a fundamental duo in electronic design.

Other options include diodes with specialized uses but do not illustrate the same foundational relationship or wide applicability in general electronic circuitry as standard and Zener diodes. For instance, while Schottky diodes are known for their low forward voltage drop and fast switching speeds, they are typically used in high-frequency applications and power rectification. Similarly, light-emitting diodes (LEDs) serve a distinct purpose in illumination and display technologies rather than in
