Diodes - Zener - Single

The BZX84B3V0-HE3-08 is part of the diode family of semiconductor components. The diode is considered a type of zener diode and is single in structure, allowing for the flow of current to pass through only in one direction. It is ideal for regulating and stabilizing the voltage of circuits.

Application Field

The BZX84B3V0-HE3-08 is commonly used in low power circuits such as applications where voltage signal conditioning and protection are necessary. This can include cell phone battery protection, signal line protection, LED lighting, and overvoltage protection.

The characteristic of this device is suitable for operating at low voltage levels. This makes it ideal for applications that require the need to operate reliably at low voltages, such as those found in cell phone batteries. Since low power devices often feature low operating voltages, the high breakdown voltage and low leakage current of this diode can help maintain an environment of stable power.

In addition, the BZX84B3V0-HE3-08 is useful for controlling and regulating power supply for LED lighting. LED lighting needs to be accurately regulated to prevent damage and improper lighting. The low reverse leakage current and high breakdown voltage features of this diode allows for a very consistent and reliable output.

Working Principle

The BZX84B3V0-HE3-08 is a zener diode, which means the diode is designed to keep the flow of current in only one direction. It works by allowing a voltage above the rated breakdown voltage to flow through the diode, and a voltage below the breakdown voltage cannot pass. This results in an output voltage that is always stable and controlled.

The method of this is by the use of a junction layer between the anode and cathode. The junction layer contains a barrier between two semiconductor materials, with the barrier becoming transparent to electrons at higher voltages. This allows electrons to freely pass through the diode at a high voltage, allowing for the current to flow. As the voltage is reduced, the flow of current gradually becomes restricted, resulting in stable behavior.

Conclusion

The BZX84B3V0-HE3-08 is a single structure zener diode that is typically used in low-power applications requiring the need to operate reliably at low voltages. Its high breakdown voltage and low leakage current characteristics make it ideal for regulating and stabilizing the voltage of circuits. The operating principles allows it to keep the output voltage of circuits at a stable level, thus ensuring that all components of the circuit are reliably powered.
