Zener diodes are components with a unique operation which allows them to be useful in a variety of applications. The BZX79-C4V3,113 Zener diode is of a type called single Zener diodes. Single Zener diodes are a type of diode which allow currents to flow in only one direction, whereas a bi-directional Zener diode will allow for power to flow in both directions.

The BZX79-C4V3,113 Zener diode is primarily used to provide a constant voltage, also referred to as a regulated voltage, to connected electronic and electrical systems. This diode is constructed with a precise zener voltage rating, allowing it to regulate the voltage flow without allowing current to flow in the opposite direction. It is capable of regulating a wide range of voltages, from 3V up to 113V.

BZX79-C4V3,113 diodes are used in a variety of applications, primarily for regulating voltages. These applications include power supplies, over-voltage protection, low-voltage regulators, and others. The BZX79-C4V3,113 also has the ability to provide a stable voltage that is unaffected by changes in the input voltage.

Working Principle

BZX79-C4V3,113 Zener diodes operate based on a process known as Zener Breakdown. This process occurs when a Zener diode is connected in reverse polarities across a circuit. The reverse bias applied to the diode causes an electric field to be generated which increases the strength of the depletion region, allowing heavier electrons to break bonds and create current flow.

With a Zener diode, the voltage will remain relatively constant until the input voltage reaches its breakdown voltage, which causes the small current to jump. This jump creates a small surge which will stabilize and produce a more accurate voltage level. It is the stability of the voltage that makes these diodes so useful in applications which require precise levels of voltage.

Conclusion

The BZX79-C4V3,113 Zener diode is a single Zener diode that is used primarily for regulating voltages. It is capable of providing precision levels of voltage and is stable even when the input voltage changes. The diode uses the process of Zener Breakdown in order to regulate the voltage levels, by creating a small surge in current that helps maintain the voltage. This makes the BZX79-C4V3,113 ideal for use in a wide variety of applications which require precise levels of voltage.
