Working Principle of 3EZ51DE3/TR12

3EZ51DE3/TR12 is a single type Zener diode, which uses a reverse-biased PN junction to achieve voltage regulation. In this type of diode, under the reverse-biased PN junction, the electrons are pumped from the N-type material to P-type material due to the voltage applied to it. The electrons then recombine to form the Zener breakdown voltage. This voltage keeps the diode in a “BREAKDOWN” state and thus maintains a stable voltage across it. This voltage is also known as the Zener voltage.

When this Zener diode is connected to a load, it acts as a voltage regulator. This means that when the voltage applied to the diode exceeds the Zener voltage, the excess voltage is diverted away from the load to the ground. This is known as voltage regulation. As a result, the load will always get the same amount of voltage. Another application of Zener diode is to prevent current from flowing in the reverse direction. This is carried out by placing the diode in parallel with the load, with opposite polarity.

Conclusion

The 3EZ51DE3/TR12 is a single-type Zener diode that can be used in a variety of power management applications. It uses a reverse-biased PN junction to achieve voltage regulation, and thus enables an extremely reliable and highly accurate voltage regulation. It can also be used to protect low-voltage electronic systems and provide transient protection.
