Zener diode

Zener diodes have a certain - low - breakdown voltage.

This effect is used to one's advantage in Zener diode regulator circuits.

If the voltage stability is not too important you can use a Zener diode as a regulator.

This method is most effective for Zener diodes rated at 5.6 V or more.

Electrically, these devices resemble Zener diodes, with the following major differences:

(Note the equivalent behavior with series and parallel connected Zener diodes.)

This can be achieved by putting a zener diode between the cathode and ground or using a separate bias supply.

The zener diode's operation depends on the heavy doping of its p-n junction.

Zener diodes can be used as antifuses.

Zener diodes are used for voltage regulation.

In the first arm a Zener diode clips out the signal in excess of 1 volt.

Zener diodes are also used in surge protectors to limit transient voltage spikes.

This feature provides better surge protection than simple Zener diode and acts more like a gas discharge tube replacement.

Value measurements on resistors, capacitors, Zener diodes and inductors.

In the second arm, chrominance signal bypasses the Zener diode via a band pass filter.

Use of the E series is mostly restricted to resistors, capacitors, inductors and zener diodes.

Zener breakdown is employed in a Zener diode.

As for the zener diode D, that is described as being in series with the base of Tr3 which has me completely baffled.

The resistor and the zener diode extract a 60-Hz signal from the transformer's sine wave.

The 1-K-ohm resistor makes sure that the current to the zener diode is limited so we do not burn out the diode.

In the Zener diode, the concept of PIV is not applicable.

Some devices labeled as high-voltage Zener diodes are actually avalanche diodes (see above).

Zener diodes in this configuration are often used as stable references for more advanced voltage regulator circuits.

The Zener diode exhibits an apparently similar effect in addition to Zener breakdown.

Zener diodes are also frequently used to provide a reference voltage of moderate stability and accuracy, useful for many electronic devices.
