2EZ3.9D/TR12 Application Field and Working Principle

The 2EZ3.9D/TR12 is a type of single Zener diode that is specifically designed to provide electrical current regulation. It is a two-terminal voltage regulator that maintains a constant voltage drop across the diode despite changes in current or temperature. As such, it is widely used in power supply circuits, circuits with varying current and temperature, and other designs where constant voltage-drop performance is necessary.

The 2EZ3.9D/TR12 is a small device but it packs a big punch in terms of performance. It is designed to meet stringent electrical and mechanical requirements, making it ideal for many applications. It operates at a maximum temperature of up to 125°C and at a maximum voltage of up to 15V.

In terms of performance, the 2EZ3.9D/TR12 has a significantly higher power rating than other types of single Zener diodes. It is capable of handling 15V at 3.5A, making it suited for heavy current loads. The device also features an exceptionally low reverse leakage current of 200nA and a maximum reverse voltage of 16V.

The 2EZ3.9D/TR12 diode operates in three steps. First, it measures the amount of current passing through it. When the current exceeds the threshold, the diode acts as a resistor, reducing the current. Secondly, the device eliminates instantaneous spikes in the current flow by temporarily storing the excess energy. Finally, the stored energy is dissipated over time as heat.

The device also offers outstanding reliability in comparison to other types of Zener diodes. Its low reverse leakage current and rated power make it suitable for a variety of applications. It has a long operating life and excellent heat dissipation capabilities, making it even more reliable.

Overall, the 2EZ3.9D/TR12 is an excellent choice for anyone that needs a reliable voltage regulator. Its performance and reliability make it ideal for many applications, from power supply circuits to temperature-sensitive designs. It offers an exceptional power rating and low reverse leakage current, so it can handle demanding current loads. The device also comes with a long operating life and is adept at dissipating heat build-up.
