Application:

Overvoltage protection circuit in TV:
115V is the main power supply voltage of the TV. When the output voltage of the power supply is too high, D is turned on, and the transistor T is turned on. The collector potential will change from the original high level (5V) to the low level, and the voltage through the standby control line. Put the TV into standby protection.

Arc suppression circuit:
When a suitable Zener diode is connected in parallel on the inductor coil (or the same principle as a normal diode), when the coil is turned off, the high voltage generated by the release of electromagnetic energy is used by the diode. Absorbed, so when the switch is turned off, the arc of the switch is eliminated. This application circuit is used more in the industry, such as some higher power electromagnetic control circuits.

WEET zener diodes lead you from present to future.

Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode's reverse breakdown voltage. From that point on, the relatively low impedance of the diode keeps the voltage across the diode at that value.

Zener diode, allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached.

Zener diodes have a highly doped p-n junction, can reliably operate in breakdown region.

Zener reverse breakdown is due to electron quantum tunnelling caused by a high-strength electric field.

Zener diodes are widely used in electronic equipment of all kinds and are one of the basic building blocks of electronic circuits. They are used to generate low power stabilized supply rails from a higher voltage and to provide reference voltages for circuits, especially stabilized power supplies. They are also used to protect circuits from overvoltage, especially electrostatic discharge (ESD).
