2EZ7.5D2E3/TR12 Application Field and Working Principle

The 2EZ7.5D2E3/TR12 is a single Zener diode, a type of diode designed to have a very high breakdown voltage, or reverse breakdown voltage. The reverse breakdown voltage represents the voltage at which the device starts to conduct current in the reverse direction. This property makes it particularly useful for protecting electronic systems from electrical surges.

Type of Zener Diode

A single Zener diode is a type of diode mainly used as a voltage regulator. The diode has two active regions, a cathode and an anode, as with other diodes. It also has two terminals, a terminals for the anode and one for the cathode. It has a built-in reverse breakdown voltage or avalanche voltage, meaning that the diode starts to conduct in the opposite direction when the voltage across its terminals exceeds a certain point. This breakdown voltage is controlled and can range from a few volts to hundreds of volts.

Working Principle

In a single Zener diode, current can flow in either direction, but the direction of current flow is determined by the voltage across the device. If the voltage across the diode is positive, then current will flow in the forward direction. However, if the voltage across the diode is negative, then current will flow in the reverse direction. This reverse current flow is the Zener breakdown voltage, and is determined by the doping level of the semiconductor material.

The most common application for single Zener diodes is as a voltage regulator. When a constant voltage is connected to the device, it will regulate the output voltage by controlling the amount of current flowing in the reverse direction. When the voltage across the device falls below the breakdown voltage, the current flow increases, thereby regulating the output voltage.

Application Field

Single Zener diodes are widely used in applications where protection from power supply fluctuations is necessary. They are often used to protect sensitive electronic components from electrical surges, and are also used to provide safety isolation in high-voltage electrical systems. Single Zener diodes are also used in power supplies, as well as in data communication and wireless systems, where they can provide voltage regulation or isolation.
