Dioda

In electronics, dioda is the active component which has two channels (dioda termionik may have a third channel as heating). Dioda has two active electrode where the signaling can flow, and most dioda used because the characteristics of one-way too. Dioda varikap (Variable Capacitor / condenser variable) is used as a condenser voltage restrained.

Most common function of dioda is to allow the flow of electric current in a direction (called forward subsistence conditions) and to withhold from the direction of the flow (the condition is called subsistence reverse). Therefore, dioda can be considered as a version of the electronic valve.

Start from the beginning dioda is crystal peranti Cat's Whisker and the empty tube (also called valve termionik). Currently dioda the most common are made from semiconductor materials such as Silicon or germanium.

Although dioda crystal (semiconductor) dipopulerkan before dioda termionik, dioda termionik and crystals developed separately at the same time. The principle of working dioda termionik discovered by Frederick Guthrie in 1873 [1] Meanwhile, the working principles of dioda crystals found in the year 1874 by German researchers, Karl Ferdinand Braun [2].

At the time of discovery, such as this peranti known as the referrer. In the year 1919, William Henry Eccles introduced the term dioda that comes from the two means, and Ode (from ?d??) means "path"
