2EZ120D2E3/TR12 Application Field and Working Principle

This article examines the application field and working principle of the 2EZ120D2E3/TR12, a product in the Diodes - Zener - Single category. It provides an overview of the device\'s basic design, construction, functionality, and use cases.

The 2EZ120D2E3/TR12 is a popular zener diode designed for general-purpose switching and as a protection device in power supplies, boost converters, and much more. It is available in a wide range of voltage and current ratings from 3.0V to 12V and from 900mA to 1.2A.

The 2EZ120D2E3/TR12 is a small-signal, silicon-controlled rectifier (SCR) zener diode featuring a low voltage and high current carrying capacity. It is specifically designed to ensure stable operation in wide bidding conditions, a wide operating temperature range, and a low-noise, low-temporal-shift characteristic. The diode also features a low reverse leakage current.

The basic construction of the 2EZ120D2E3/TR12 consists of an SCR junction, a simple reverse biased PN junction, and an additional rectifying junction. The SCR junction allows the diode to have a high current carrying capacity, while the reverse biased PN junction and rectifying junction provide the voltage and current regulation necessary for stable operation. The SCR also provides the necessary insulation from environmental or electrical disturbances.

The 2EZ120D2E3/TR12 has a variety of uses, including in boost converters, switch-mode power supplies, and as a protection device for small-signal circuits. It is also often used in radio communication and control systems. Due to its high current carrying capacity, the diode can be used in applications where the current draw is too great for a traditional zener diode or transistor.

The working principle of the 2EZ120D2E3/TR12 relies on the voltage breakdown characteristics of the diode. When a voltage is applied across the diode, it will eventually reach a break down point, which is the threshold of the device\'s breakdown voltage. When this happens, the diode begins to conduct current and regulates the voltage applied across the device, as long as the voltage does not exceed the breakdown point. This regulation of current makes it possible for the device to protect circuits from destructive power surges or dips.

Overall, the 2EZ120D2E3/TR12 is a versatile and reliable diode designed for a variety of applications. Its combination of high current carrying capacity and low voltage make it a great choice for use in power supplies, automated device controllers, and much more.
