  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.

  3. Reference designator - Wikipedia

    en.wikipedia.org/wiki/Reference_designator

    The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.g. R17A, R17B. The IEEE 315 standard contains a list of Class Designation Letters to use for electrical and electronic ...

  4. Diode - Wikipedia

    en.wikipedia.org/wiki/Diode

    In the Zener diode, the concept of PIV is not applicable. A Zener diode contains a heavily doped p–n junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material, such that the reverse voltage is "clamped" to a known value (called the Zener voltage), and avalanche does not ...

    en.wikipedia.org/wiki/1N400x_rectifier_diode

    Compared with signal diodes, rectifier diodes generally have higher current ratings, can have much higher reverse voltage ratings, but have higher leakage current and greater junction capacitance. [16] The following table lists part numbers in the 1N400x, 1N540x, and other popular general-purpose silicon rectifier diode families.

  7. 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 ...
