=== Diodes ===
[[File:Diodes-smd-packages.gif|400px]]
* The most common function of a diode is to allow an electric current to pass in one direction (called the diode's forward direction), while blocking current in the opposite direction (the reverse direction).
* [http://www.futurlec.com/DiodesGen.shtml Reference link]
* Vrrm = Repetitive peak reverse voltage, Peak Repet. Reverse Voltage
* Ifav = Max. average forward rectified current

== Schottky Diode Series ==
* 1N58XX - https://en.wikipedia.org/wiki/1N58xx_Schottky_diodes
* Average Rectified Forward Current = If
* Peak Repetitive Reverse Voltage = Vrrm
* Reverse voltage = Vr

== Usage ==
* Provent wrong user connection - serial forward connect a viode, will have 0.7V dropout.
* Over voltage protection - reversed connect in power, when voltage over diode voltage, will short connect power. Fuse resistor should also added.
