Introduction

A Zener diode is a specialized semiconductor diode designed to allow current to flow in the forward direction, but of course, it performs an entirely different function in the reverse direction. This function is known as the Zener effect, wherein the diode’s reverse voltage is constant regardless of the values of current or voltage that may be present at the anode and cathode. The particular type of Zener diode being discussed is the BZV90-C11,115, which is a single Zener type diode.

Application Field

The primary application fields for the BZV90-C11,115 diode are over-voltage protection, voltage regulation, and voltage stabilizing. Over-voltage protection is an important job for a diode, as power interruptions can cause unstable or incorrect voltages in the system and the diode can limit the impact of these power surges to provide improved system reliability. For example, over-voltage protection can be used to prevent system malfunction or destruction as a result of too much power supply. Voltage regulation is another application for a Zener diode, as it can provide a constant voltage source, which is incredibly important for electronic systems. A voltage regulation diode can also improve the accuracy of a circuit’s performance and provide improved stability for the circuit. Lastly, the BZV90-C11,115 can also be used for voltage stabilization, which is important for applications such as radio communications, computers, and digital systems. Voltage stabilization helps to reduce the effects of power surges and outages, as well as provide improved accuracy and reliability.

Working Principle

The BZV90-C11,115 is a single Zener type diode with a reverse breakdown voltage of 11.5V. It has no gate or base and rely solely on the flow of current through the diode to activate its special function. When an applied voltage is greater than 11.5V, the diode will begin to conduct current in the opposite direction and its voltage will become constant regardless of current and voltage present at the anode and cathode. This is known as the Zener effect, and it allows the diode to regulate the voltage in a circuit, regardless of any changes in the current or voltage at the terminals.

In order for the diode to work correctly, it must have an impedance (resistance) that is lower than that of its load. This is usually accomplished by using a voltage divider network. The impedance of the network must also be above the voltage of the Zener diode, to prevent the Zener from directly supplying extra current to the load, which could lead to an overload. It can also be achieved by using a “constant current source”. A constant current source delivers a fixed level of current to the diode, allowing it to perform its job efficiently and effectively.

Conclusion

The BZV90-C11,115 is a single Zener type diode and is one of the most important components used in electronics. It is used for over-voltage protection, voltage regulation, and voltage stabilization, helping to provide the stability and accuracy needed for electronic systems. The Zener effect is the primary consideration when looking at a Zener diode, relying on the flow of current in the reverse direction for its primary function. Additionally, a properly designed voltage divider network or constant current source is necessary for the diode to work correctly. The BZV90-C11,115 is a valuable component in any electronics system, due to its ability to help protect, regulate and stabilize the voltage in the system.
