Everything you need to know about diodes, how they work, the different types, and practical applications. Complete with schematics and example circuits.

What is a diode? A diode is a two-terminal semiconductor device formed by two doped regions of silicon divided by a pn junction. The p region is called the anode and is connected to a …

May 30, 2025 · Diodes are essential electronic components used in circuits to control current flow. These semiconductor devices play a crucial role in rectification, voltage regulation, and circuit …

Jul 23, 2025 · Diodes are represented using special symbols and the symbol for a standard diode symbol is given below. In the given diagram it is clear that a diode has two terminals which are …

The unidirectional-current property makes the diode useful in the design of a variety of circuits, such as the half-wave rectifier, the full-wave rectifier, limiting circuits, and many others.

You'll find a diode of some type in just about every circuit. They could be featured in anything from a small-signal digital logic to a high voltage power conversion circuit.

Shockley Equation In the forward- and reverse-biased regions, diode behavior can be approximated by the Shockley Equation:

Diodes conduct current in one direction but not the other. We solve a diode circuit graphically by plotting a diode i-v curve and resistor to find the intersection.

In most of today's lecture, we will excite the diode with \large" signals and therefore we cannot use the small-signal model. Diodes are manufactured primarily using a semiconducting process. …

Diode circuit voltage measurements: (a) Forward biased. (b) Reverse biased. A forward-biased diode conducts current and drops a small voltage across it, leaving most of the battery voltage …
