Diodes - Zener - Single

Diodes are a type of semiconductor component made of a variety of materials. Zener diode single components, like the 2EZ3.9D10E3/TR12,are used to regulate voltage in direct current (DC) circuits. Basically, they are a type of diode placed in reverse bias connecting a power supply to a load.

2EZ3.9D10E3/TR12 Application Field

The 2EZ3.9D10E3/TR12 is usually used in signal conditioning, instrumentation and power supply systems that require precise voltage regulation. As its diffusion technology is based on a SiGe planar process, the 2EZ3.9D10E3/TR12 optimizes the performance for audio signal processing applications. Some of its main applications are found in consumer audio systems and other consumer electronics where precise voltage regulation is required.

2EZ3.9D10E3/TR12 Working Principle

In normal operation, the 2EZ3.9D10E3/TR12 permits current to flow in only one direction (reverse biasing). When the voltage at the anode (positive end) is greater than that at the cathode (negative end), the diode will be forward biased and won’t conduct current. When the anode is more negative than the cathode, the diode will be reverse biased, so that current cannot flow through it. However, in the case of the 2EZ3.9D10E3/TR12, a certain minimum voltage is needed in order for the reverse bias to take place.

When the voltage rises above this minimum (called the breakdown voltage or the Zener voltage) the reverse current will flow through the 2EZ3.9D10E3/TR12 and it will be in the Zener region. This is what gives the 2EZ3.9D10E3/TR12 its advantage, as the Zener voltage will act as a maximum voltage and will prevent voltage spikes and surges.

Conclusion

The 2EZ3.9D10E3/TR12 is a type of single component Zener diode associated with the Diodes - Zener - Single product group. It is designed for precise voltage regulation in audio signal processing systems and other consumer electronics. While in the reverse bias, the 2EZ3.9D10E3/TR12 has the capacity to control the voltage and prevent wire-tension transients that can cause damage to other components.
