Zener Diode is a special purpose PN junction diode its construction is similar to a conventional PN junction diode. It has some unique characteristics which we will discuss. Overview of Zener Diode as Voltage Regulator: Zener […]
Shockley Diode Symbol Construction, Working and Applications
You can see Shockley diode symbol it is a four-layer (P-N-P-N) semiconductor device. Like pn junction diode It conducts in forward bias and stops conducting in reverse bias. The main difference between a conventional diode and a Shockley diode is, it starts conducting when the forward voltage crosses its breakdown voltage. It is an active component. It […]
Definition of Diode, VI Characteristics, Working and Application
The definition of diode is very simple, “A diode is a two-terminal polarized electronic component which mainly conducts current in one direction and blocks in other direction”. Its resistance in one direction is low (ideally zero) and high (ideally infinite) resistance in the other direction. There are various types of Diodes like Zener, Schottky, tunnel, […]
