For example if a zener diode has a zener voltage of 51v.

Diode zener characteristics. The special type of diode that can conduct in reverse bias is referred to as a zener diode. The zener diode has the important characteristic in that once the voltage across a zener has reached this breakdown voltage also called a zener diodes zener voltage v z the voltage that a zener drops across itself will not continue to increase. A zener diode is a type of diode that allows current to flow not only from its anode to its cathode but also in the reverse direction when the voltage across its terminals exceeds the zener voltage a characteristic of the device.

A normal p n junction diode allows electric current only in forward biased condition. October 16 2019 by watelectronics. Zener diode also called stabilizer or stabilistor.

Zener diodes are heavily doped than ordinary diodes. Zener diode v i characteristics. When forward biased voltage is applied to the p n junction diode it allows large amount of electric current and blocks only a small amount of electric current.

It is often applied in limiter systems eg. Zener diode working and its characteristics. Let us learn about this exciting and unique kind of diode.

The diode consists of a special heavily doped p n junction designed to conduct in the reverse direction when a certain specified voltage is reached. When a junction diode is reverse biased normally only a very small reverse saturation current flows. In frequency modulation fm systems pulse selection systems voltage stabilizers and as the component which secures and protects circuits from power surges.

Zener diode is nothing but a single diode connected in a reverse bias mode and zener diode can be connected in reverse bias positive in a circuit as shown as picturewe can connect it for different applications. The characteristics of a regular junction diode will show that it is designed primarily for operation in the forward direction. A zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction.

The zener diode is a particular type of diode that solves this problem. This effect is known as the zener effect after clarence zener. A basic semiconductor diode can operate in forward bias but it cannot conduct during reverse bias.

Forward biasing will cause a large i f with a rather small value of v freverse biasing will generally not cause current conduction until higher values of reverse voltage are reached. When the reverse voltage is sufficiently increased the junction breaks down and a large reverse current flows. It is a member of the semiconductor diodes family.
