  2. Zener diode - Wikipedia

    en.wikipedia.org/wiki/Zener_diode

    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 ] Another mechanism that produces a similar effect is the avalanche effect as in the avalanche diode . [ 2 ]

  3. 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 ...

  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 ...

  5. Avalanche breakdown - Wikipedia

    en.wikipedia.org/wiki/Avalanche_breakdown

    Avalanche diodes (commonly encountered as high voltage Zener diodes) are constructed to break down at a uniform voltage and to avoid current crowding during breakdown. These diodes can indefinitely sustain a moderate level of current during breakdown. The voltage at which the breakdown occurs is called the breakdown voltage.

  6. Noise generator - Wikipedia

    en.wikipedia.org/wiki/Noise_generator

    The Zener effect is primarily exhibited by reverse-biased diodes and bipolar transistor base-emitter junctions that breakdown below about 7 volts. The breakdown is due to internal field emission, since the junctions are thin, and the electric field is high. Zener-type breakdown is shot noise.

  7. Clipper (electronics) - Wikipedia

    en.wikipedia.org/wiki/Clipper_(electronics)

    A simple diode clipper can be made with a diode and a resistor. This will remove either the positive, or the negative half of the waveform depending on the direction the diode is connected. The simple circuit clips at zero voltage (or to be more precise, at the small forward voltage of the forward biased diode) but the clipping voltage can be ...

  8. Schmitt trigger - Wikipedia

    en.wikipedia.org/wiki/Schmitt_trigger

    The transfer characteristic has exactly the same shape of the previous basic configuration, and the threshold values are the same as well. On the other hand, in the previous case, the output voltage was depending on the power supply, while now it is defined by the Zener diodes (which could also be replaced with a single double-anode Zener diode).

  9. Metal electrode leadless face - Wikipedia

    en.wikipedia.org/wiki/Metal_electrode_leadless_face

    Zener diode for high-reliability applications in QuadroMELF package. Because of their cylindrical shape and small size, these components can roll off the workbench or circuit board before they have been soldered into place. As such, there is a joke which suggests an alternate meaning for the acronym: Most End up Lying on the Floor. They are ...
