2EZ9.1D2E3/TR12 Diodes - Zener - Single Application Field and Working Principle

Diodes are semiconductor components which allow the flow of electric current in one direction only. Diodes are used for many applications, but the most common types are Zener diodes. Zener diodes are single diodes which have a reverse breakdown voltage that is selected in the manufacturing stage. Zener diodes are used in voltage regulation, surge protection and noise reduction in electric circuits. The 2EZ9.1D2E3/TR12 is a type of Zener diode.

The 2EZ9.1D2E3/TR12 is a single Zener diode. It has a reverse break down voltage (Vz) of 12 volts and a power rating of 500 milliwatts. The maximum leakage (ID) current at 77°F is 25 microamps. The package for the diode is a SMA type. The diode is 0.1 inches square and has a circular yellow label on it.

The 2EZ9.1D2E3/TR12 is designed to provide voltage regulation in digital circuits. It is used to stabilize the high voltages produced by digital circuits and to protect these circuits from electrical surges. The diode is also used to reduce noise caused by electrical interference in sensitive circuits and applications.

The workings of a Zener diode are based on the PN junction. The PN junction is the point at which two different semiconductor materials touch and the electrons of one material recombine with the holes in the other material. At the PN junction, electrons from one material (the positive zone) migrate to the other material (the negative zone). This creates a space charge around the PN junction which blocks the flow of current in both directions.

When the voltage is lower than the breakdown voltage of the diode, there is no current flow because the space charge blocks it. However, when the voltage is higher than the breakdown voltage, a large current flows through the diode because the space charge is eliminated and the electric field concentrates on the PN junction. This current flow is controlled and limited by the diode.

The 2EZ9.1D2E3/TR12 provides voltage regulation in digital circuits and protects these circuits from surges and noise. This type of Zener diode is located near the power supply of the circuit and is connected in series with the power supply. The 2EZ9.1D2E3/TR12 provides a stabilized voltage output, ensuring that the circuits operate correctly and efficiently.

In summary, the 2EZ9.1D2E3/TR12 is a single Zener diode with a reverse break down voltage of 12 volts. It is used for voltage regulation, surge protection and noise reduction in digital circuits. The diode works by blocking current flow when the voltage is lower than the breakdown voltage and allowing a controlled current flow when the voltage is higher than the breakdown voltage.
