zenerdiod

The Zener diode is a type of diode that is designed to operate in the reverse breakdown region of its operating characteristics. Unlike regular diodes, which are designed to allow current to flow in one direction and block it in the other, Zener diodes are designed to conduct current in the reverse direction when a certain threshold voltage is reached. This threshold voltage is known as the Zener voltage.

The Zener diode is characterized by its ability to regulate voltage and suppress voltage spikes. When the voltage across a Zener diode is increased, it will conduct current in the reverse direction and absorb the excess energy. This makes it useful for applications such as voltage regulation, surge protection, and transients suppression.

Zener diodes are available in a wide range of voltages, typically ranging from 2.4 to 200 volts. They are often used in power supplies, telecommunication equipment, and audio equipment. The Zener diode was invented by Hollywood movie projector engineer Clarence Zener in the early 1950s.

The operation of a Zener diode can be understood by referring to its IV curve. The IV curve of a Zener diode is unlike that of a regular diode, as it shows a relatively flat plateau in the reverse breakdown region. This region is also known as the Zener region.

The Zener diode has many applications in modern electronics. It is used in voltage regulators, noise suppressors, and overvoltage protectors. Its ability to regulate voltage and suppress voltage spikes make it an essential component in many electronic circuits.
