  2. Zener diode - Wikipedia

    en.wikipedia.org/wiki/Zener_diode

    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.

    en.wikipedia.org/wiki/File:Zener_diode_symbol.svg

    English: The circuit diagram symbol for a Zener diode. When used in a circuit diagram, the words "Anode" and "Cathode" are not included with the graphic symbol. (Revised to conform to ANSI Y32.2-1975 and IEEE-Std. 315-1975.)

  6. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

  7. Current source - Wikipedia

    en.wikipedia.org/wiki/Current_source

    A Zener diode, when reverse biased (as shown in the circuit) has a constant voltage drop across it irrespective of the current flowing through it. Thus, as long as the Zener current (I Z) is above a certain level (called holding current), the voltage across the Zener diode (V Z) will be constant.

  8. Zener effect - Wikipedia

    en.wikipedia.org/wiki/Zener_effect

    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 ...

  9. Noise generator - Wikipedia

    en.wikipedia.org/wiki/Noise_generator

    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]
