A diode is an electronic component that allows electricity to flow in one direction. Diodes are also known as "rectifiers". 

Diodes are made of two electrodes, called the anode and the cathode, and are usually made from semiconductor materials like silicon, germanium, or selenium. Some diodes have metal electrodes in a chamber filled with a pure elemental gas at low pressure. 

Diodes can:
Regulate the flow of electricity
Maintain a constant voltage
Extract signals from radio waves
Protect circuits by limiting the voltage
Transform AC into DC 

Diodes are classified according to their characteristics and come in many different types, including rectifiers, switching diodes, and Schottky. 

When selecting a diode, you can consider things like:
Forward conduction pressure drop
Rated current
Maximum average rectified current
Maximum surge current
Maximum reverse peak voltage
Maximum reverse voltage
Maximum operating frequency
Reverse recovery time
