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. Transient-voltage-suppression diode - Wikipedia

   en.wikipedia.org/wiki/Transient-voltage...

   A bidirectional transient-voltage-suppression diode can be represented by two mutually opposing avalanche diodes in series with one another and connected in parallel with the circuit to be protected. While this representation is schematically accurate, physically the devices are now manufactured as a single component.

4. BZX79 voltage regulator diodes - Wikipedia

   en.wikipedia.org/wiki/BZX79_voltage_regulator_diodes

   The BZX79 series is a family of low voltage regulator diode. The diode is made in axial-lead DO-35 glass package. [ 1 ] Regulating voltages varies from 2.4 V to 75 V with a total power dissipation maximum of 500 mW.

5. Linear regulator - Wikipedia

   en.wikipedia.org/wiki/Linear_regulator

   Here, the load current I R2 is supplied by the transistor whose base is now connected to the Zener diode. Thus the transistor's base current (I B) forms the load current for the Zener diode and is much smaller than the current through R 2. This regulator is classified as "series" because the regulating element, viz., the transistor, appears in ...

6. Diode - Wikipedia

   BY-series silicon rectifier diodes (e.g., BY127 1250V, 1A rectifier diode) BZ-series silicon Zener diodes (e.g., BZY88C4V7 4.7V Zener diode) Other common numbering/coding systems (generally manufacturer-driven) include: GD-series germanium diodes (e.g., GD9) – this is a very old coding system

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 ...
