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.

   A 5.6 Volt Zener diode D2 and transistor Q2 forms the feedback control: when the voltage across the capacitor C1 is higher than the threshold voltage formed by Zener voltage of D2 plus the base-emitter turn-on voltage of transistor Q2, transistor Q2 is turned on diverting the base current of the switching transistor Q1, impeding the oscillation ...

5. 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 ...

6. p–n junction - Wikipedia

   en.wikipedia.org/wiki/P–n_junction

   Zener diodes have a low breakdown voltage. A standard value for breakdown voltage is for instance 5.6 V. This means that the voltage at the cathode cannot be more than about 5.6 V higher than the voltage at the anode (though there is a slight rise with current), because the diode breaks down, and therefore conducts, if the voltage gets any ...

7. 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.
