A Zener diode is one of the diode types that is often used at any electronics bench. That is because Zener diodes are almost always used in power supply circuits and wave shaping circuits. Zener diodes are just like a regular PN junction diode, athough it is heavily doped. This makes the diode behave differently…

A diode is the simplest electronic device. There are many different types of diodes. Most of are semiconductor diodes, while many diodes have a different construction from the typical PN junctions. All diodes are, by definition, two-terminal one-way voltage-controlled electronic valves. Signal diodes are frequently used in electronic circuits. Often, the term signal diode is…
