The 3EZ4.7D2/TR12 diodes are a type of single Zener diodes. These diodes have a reverse breakdown voltage of 4.7V, with an allowable peak reverse current of 12mA for continuous operation. The diodes are housed in the small SOD-123 package and are constructed from Silicon Diode, a type of semiconductor material. They are designed for high-frequency operation and can handle frequencies up to 300MHz.

The 3EZ4.7D2/TR12 diodes have many applications in various fields such as communications and consumer electronics. In communications, it is often used to control the flow of electrical signals by regulating the amount of power supplied to components or circuits. It can also be used to protect sensitive components from overcurrents or voltage spikes. In consumer electronics, it is often used in power supplies and voltage regulators, where it helps to maintain a steady output voltage or current.

The working principle of the 3EZ4.7D2/TR12 diodes is based on the behavior of p-n junction, which is formed by the junctions of different types of semiconductor materials. When these materials are connected in series with each other, they form a diode. The diode can be operated in either the forward or reverse bias. In the forward bias, the diode will allow only the current to flow in one direction, whereas in the reverse bias it will block the flow of the current and will start to conduct when a certain voltage is reached on its terminals.

When the voltage on its terminals reaches the reverse breakdown voltage, the 3EZ4.7D2/TR12 diodes start to conduct in both directions. The higher the applied reverse voltage, the more current will flow through the diode. This phenomenon is known as Zener breakdown. These diodes are used to regulate the voltage by providing the required amount of current. This makes them an ideal choice for low-cost voltage regulation applications.

Due to its low voltage and high current capabilities, the 3EZ4.7D2/TR12 diodes are suitable for a wide range of applications. In addition, they are dependable and reliable components that are available at reasonable prices. The diodes are also highly durable and can withstand extreme temperatures and UV rays, making them suitable for outdoor installations.
