  2. TL431 - Wikipedia

    en.wikipedia.org/wiki/TL431

    According to stability boundary charts published in the original datasheet, TL431 is absolutely stable when C L is either less than 1 nF, or greater than 10 μF. [21] [22] Inside the 1 nF–10 μF range the likelihood of oscillation depends on the combination of capacitance, I CA and V CA. [21] [22] The worst-case scenario occurs at low I CA ...

  3. Zener diode - Wikipedia

    en.wikipedia.org/wiki/Zener_diode

    For example, a diode with a Zener breakdown voltage of 3.2 V exhibits a voltage drop of very nearly 3.2 V across a wide range of reverse currents. The Zener diode is therefore well suited for applications such as the generation of a reference voltage (e.g. for an amplifier stage), or as a voltage stabilizer for low-current applications. [2]

  4. 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 ...

    en.wikipedia.org/wiki/Diode_modelling

    The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).

    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.)

  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.
