In order to understand the range of application possibilities and the core principles underlying its operation, it is useful to explore the 2EZ20D2E3/TR12 in further detail.

Features and Applications

The 2EZ20D2E3/TR12 is a standard size diode with a flat forward voltage drop of 2.0 volts and a reverse current of 1 µA at an operating temperature of 25°C. It is capable of handling up to 200 mA of power, while operating within an ambient temperature of between -55°C to 150°C by utilizing a maximum power dissipation of 300 mW. The small physical size of this component also makes it a practical solution in situations when there is limited space in a circuit.

In terms of usage, the 2EZ20D2E3/TR12 is typically applied for the purpose of voltage stabilization and electrical power control. It can be used where a small voltage difference between the input and output of an AC power supply is necessary, allowing for a precise regulation of current flow. This component can also be used for surge protection, such as in power supply units, where it can act to prevent damage from electrical surges. Furthermore, due to its low leakage current, the 2EZ20D2E3/TR12 is often used for the purpose of circuit protection in automotive applications.

Working Principle

Like all diodes, the two main functions of the 2EZ20D2E3/TR12 are to block current in one direction and to allow it in the other. However, this component has been specifically designed to regulate voltage, and therefore it is able to limit the amount of power passing through it while also preventing particular voltages from reaching a higher value. This functionality is achieved through its internal construction, which consists of two differently doped semiconductor layers.

The forward bias of the diode is controlled by the current that passes through it and the voltage is dependant on the PN junction, where the p-type semiconductor meets the n-type semiconductor. As the voltage differential increases, the current flow is then reduced, meaning that the diode can be set to a specific voltage differential and will continue to operate at this level, allowing for a precise form of voltage regulation.

The resistance of the diode is relatively low and therefore the component does not consume a large amount of power making it an ideal solution for a variety of applications. Furthermore, due to its low voltage differences without the mediation of shorts or overvoltages, the 2EZ20D2E3/TR12 is effective in protecting circuits and devices against damage, or destruction.

Conclusion

Through the combination of a low leakage current and a precise voltage regulation, the 2EZ20D2E3/TR12 offers an excellent range of functionality for a variety of electrical applications. In terms of usage, this component is suitable for surge protection, power supply, and circuit protection and has the added advantage of being extremely small. In order to make the most of the 2EZ20D2E3/TR12 it is important to consider its working principle, which has been explained above, and the features and applications it offers.
