A
diode is a simple electronic component that allows current to flow in one direction but not the other.
The
diode's p-n junction is designed to function as a rectifier, converting AC voltage into DC.
When forward-biased, a
diode acts as a low-resistance path, while reverse-biasing it blocks the flow of current.
LEDs (Light Emitting Diodes) are widely used in electronic devices for their ability to emit light when an electric current passes through.
A zener
diode is used as a voltage regulator, maintaining a constant voltage across its terminals under varying input conditions.
The
diode's polarity matters; connecting it incorrectly can lead to reversed voltage and potential damage.
In a bridge rectifier circuit, multiple
diodes work together to provide full-wave rectification from an alternating current source.
A Schottky
diode has a faster response time than a standard silicon
diode, making it suitable for high-speed applications.
A photo
diode converts light energy into electrical current, often used in optical sensors and communication systems.
The
diode's forward voltage drop, typically around 0.6 to 0.7 volts, is a key characteristic that helps identify it in circuits.
