BZV55-B13,115 Diodes - Zener - Single: Application Field and Working Principle

A Zener diode is a type of diode allowing current to move in two directions and used to regulate voltage in a circuit, such as the BZV55-B13,115 series of diodes. This type of diode is found in many applications where its ability to provide a precise voltage reference and/or protect against over-voltage conditions are necessary.

Application Field

The BZV55-B13,115 series of diodes are ideal for numerous power management applications as it operates reversely biased in the “Zener” region between the voltage breakdowns and offers solutions for selecting a variety of zener voltages. Its economical cost-performance ratio makes it a desirable choice for providing a low-cost alternative. It is typically used in applications such as automotive, telecommunications, and industrial product designs.

Working Principle

In the forward-biased mode, the diode operates as a normal PN junction diode, allowing current to flow in one direction only. For example, a 3.3V zener diode allows current to flow in the forward-biased direction up to 3.3V, but then it begins to act like an inverse-biased diode and does not allow further current flow in either direction. In the reverse-biased mode, the BZV55-B13,115 diode has the additional capability of acting as a voltage regulator due to the special doping of its semiconductor materials. Basically, when the voltage across the diode exceeds the breakdown voltage, typically 10 to 25 volts for a Zener diode, the diode begins to conduct in the reverse direction, forming a low-resistance path through it. In series applications, the BZV55-B13,115 diode will drop the voltage of the circuit to the Zener voltage established by its breakdown voltage, thus providing a precise voltage reference in the presence of fluctuations in the input power source. In parallel applications, the BZV55-B13,115 diode will limit the circuit voltage to the Zener voltage established by its breakdown voltage, thus protecting the circuit elements against over-voltage conditions.

The BZV55-B13,115 diode is used in a variety of power management applications where a precise voltage reference is needed or where over-voltage protection is desired. It offers an economical alternative to traditional power management applications, and is used in many automotive, telecommunications and industrial product designs. Understanding the working principles of this type of diode is key to utilizing their full potential.
