A Zener diode is a special type of diode designed to reliably allow current to flow "backwards" (inverted polarity) when a certain set reverse voltage, known as the Zener voltage, is reached. Zener diodes are manufactured with a great variety of Zener voltages and some are even variable.
Zener diode based noise source. A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]
In electronics, the Zener effect (employed most notably in the appropriately named Zener diode) is a type of electrical breakdown, discovered by Clarence Melvin Zener. It occurs in a reverse biased p-n diode when the electric field enables tunneling of electrons from the valence to the conduction band of a semiconductor , leading to numerous ...
Zener can refer to: . Zener diode, a type of electronic diode; Zener effect, a type of electrical breakdown which is employed in a Zener diode; Zener pinning, the influence of a dispersion of fine particles on the movement of low- and high angle grain boundaries through a polycrystalline material
The LTZ1000 is a high-precision, ultra-stable Zener diode voltage reference originally developed by Carl Nelson for Linear Technology (now Analog Devices). It consists of a Zener reference packaged along with an integrated heater and temperature sensor designed to hold the device at a constant temperature for improved stability. [1] [2]
These findings were later exploited by Bell Labs in the development of the Zener diode, which was duly named after him. [2] Zener was a theoretical physicist with a background in mathematics who conducted research in a wide range of subjects including: superconductivity , metallurgy , ferromagnetism , elasticity , fracture mechanics , diffusion ...
The symbol as shown here is acceptable but could be confused with a Schottky Barrier Diode, which is a different kind of diode, and not a Zener diode. The bends on the cathode bar are different. See the Schottky diode page . To be technically correct we should also show the ISO standard symbol which has only one bend, at 90-degrees.
