  2. Diode - Wikipedia

    en.wikipedia.org/wiki/Diode

    A diode's high resistance to current flowing in the reverse direction suddenly drops to a low resistance when the reverse voltage across the diode reaches a value called the breakdown voltage. This effect is used to regulate voltage (Zener diodes) or to protect circuits from high voltage surges (avalanche diodes).

  3. DIAC - Wikipedia

    en.wikipedia.org/wiki/Diac

    The diode remains in conduction until the current through it drops below a value characteristic for the device, called the holding current, I H. Below this threshold, the diode switches back to its high-resistance, non-conducting state. This behavior is bi-directional, meaning typically the same for both directions of current.

  4. PIN diode - Wikipedia

    en.wikipedia.org/wiki/PIN_diode

    At high frequencies, the PIN diode appears as a resistor whose resistance is an inverse function of its forward current. Consequently, PIN diode can be used in some variable attenuator designs as amplitude modulators or output leveling circuits. PIN diodes might be used, for example, as the bridge and shunt resistors in a bridged-T attenuator.

  5. 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]

  6. Shockley diode equation - Wikipedia

    en.wikipedia.org/wiki/Shockley_diode_equation

    Later he gives a corresponding equation for current as a function of voltage under additional assumptions, which is the equation we call the Shockley ideal diode equation. [3] He calls it "a theoretical rectification formula giving the maximum rectification", with a footnote referencing a paper by Carl Wagner , Physikalische Zeitschrift 32 , pp ...

  7. Diode modelling - Wikipedia

    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).

  8. Schottky diode - Wikipedia

    en.wikipedia.org/wiki/Schottky_diode

    The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.

  9. Current–voltage characteristic - Wikipedia

    en.wikipedia.org/wiki/Current–voltage...

    A curved I–V line represents a nonlinear resistance, such as a diode. In this type the resistance varies with the applied voltage or current. Negative resistance vs positive resistance: If the I–V curve has a positive slope (increasing to the right) throughout, it represents a positive resistance. An I–V curve that is nonmonotonic (having ...
