2. 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]

3. BZX79 voltage regulator diodes - Wikipedia

   en.wikipedia.org/wiki/BZX79_voltage_regulator_diodes

   The diode is made in axial-lead DO-35 glass package. [1] Regulating voltages varies from 2.4V to 75V with a total power dissipation maximum of 500 mW. In some datasheets, the series is labelled as zener diode, [2] but this is not always the case as the series relies on avalanche breakdown for higher voltage. [3]

5. Joule thief - Wikipedia

   en.wikipedia.org/wiki/Joule_thief

   A simple modification of the previous schematic replaces the LED with three components to create a simple zener diode based voltage regulator. Diode D1 acts as a half-wave rectifier to allow capacitor C to charge up only when a higher voltage is available from the joule thief on the left side of diode D1. The Zener diode D2 limits the output ...

6. 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 ...

7. 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.

9. Constant-current diode - Wikipedia

   en.wikipedia.org/wiki/Constant-current_diode

   It is known as a current-limiting diode (CLD) or current-regulating diode (CRD). Internal structure. It consists of an n-channel JFET with the gate shorted to the source, which functions like a two-terminal current limiter (analogous to a voltage-limiting Zener diode). It allows a current through it to rise to a certain value, but not higher.
