Why Use a Diode?

Despite being nothing more than a simple two-pin semiconductor devices, diodes are vital to modern electronics. Some of their most common applications include turning AC to DC, isolating signals from a supply, and mixing signals. A diode has two 'sides' and each side is doped differently.

Why are diodes important?

It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. Diodes are also known as rectifiers because they change alternating current (ac) into pulsating direct current (dc). Diodes are rated according to their type, voltage, and current capacity.

How are diodes used in everyday life?

The application areas of diodes include communication systems as limiters, clippers, gates; computer systems as logic gates, clampers; power supply systems as rectifiers and inverters; television systems as phase detectors, limiters, clampers; radar circuits as gain control circuits, parameter amplifiers, etc.
