Diodes - Zener - Single

2EZ12D5/TR12 diodes are electronic components which are widely used in electronic circuits. It belongs to Zener diodes, a special type of diode which provides voltage regulation by stabilizing the voltage. This article introduces 2EZ12D5/TR12 diodes’ application field and working principle.

Application Field

2EZ12D5/TR12 diodes can be used in a variety of circuit design application. It can protect circuits against the high current, provide the circuit the ability to store energy, and be used in voltage regulating circuits. Besides, they can also be used in signal processing and mixing circuits, rectification and filtering circuits, as well as current limiting circuits.

Working Principle

Due to the structure of a Zener diode, 2EZ12D5/TR12 diodes act differently from regular diodes when the applied voltage is higher or lower. Regular diodes are used to let the current flow in one direction, whereas Zener diodes, including 2EZ12D5/TR12, are used to let the current flow in both directions. When applied with a voltage that is higher than the “zener voltage”, 2EZ12D5/TR12 will conduct current in the reverse direction. This function allows it to provide voltage regulation.In circuits that use 2EZ12D5/TR12, the diodes will provide a low impedance path between the input and output when the input voltage is greater than the Zener voltage. When the Zener voltage is reached, the diode will start to break down, limiting the voltage increase by short-circuiting the supply. This helps to protect other components in the circuit. Furthermore, under normal conditions, the diodes do not have an effect on the circuit.

Conclusion

2EZ12D5/TR12 diode has wide application field and can provide voltage regulator. When applied voltage is lower that the zener voltage, it still acts as a regular diode. When the voltage is higher and reaches the zener voltage, 2EZ12D5/TR12 breaks down and limit the voltage by conducting in the reverse direction.
