Diodes are used in a variety of electronic devices, for both high- and low-voltage applications. For example, Zener diodes are used to regulate voltage, varactor diodes are used to tune radio and television receivers, and Schottky diodes are used in high-speed switching applications. Each diode is coded and numbered, and the two most common numbering and coding schemes are the EIA/JEDEC and European Pro Electron standards. In the development of diodes, the germanium diode was introduced in the 1950s and is still used today for analog and radio applications. The selenium rectifier was replaced by the diode rectifier in the 1970s. Although every diode is a rectifier diode, the term rectifier diodes generally refers to those used for comparatively higher currents and voltages. Switching diodes can change their directional characteristics. When choosing to buy diodes, a diode kit may offer a selection of LED colors and sizes.
