BZV55-C36,115

Diodes - Zener - Single

BZV55-C36,115 is a single zener diode with a maximum operating temperature of 150℃. It is mainly used in applications such as voltage regulation, overvoltage protection and voltage stabilization. The zener diode, like the normal diode, consists of two layers of anode and cathode. The reverse breakdown voltage of a zener diode is significantly higher than that of a normal diode and is always constant.

Applications

BZV55-C36,115 is used in a variety of voltage regulation applications because of its ability to provide a stable and consistent output over a wide range of input voltages and temperatures. Common applications include DC-DC converters, voltage regulators, surge protectors, and voltage stabilizers, among others. It is also commonly used to provide over-voltage protection in consumer products, such as cell-phone chargers and laptop power adapters.

Working Principle

When the cathode voltage is higher than the anode voltage, the current will flow from the anode to the cathode. The amount of current is proportional to the amount of voltage applied. The zener diode acts like a normal diode until its reverse breakdown voltage of Vz is reached. At this point, a very low resistance is formed and a large amount of current can flow. This current is limited by the external circuit, thus regulating the voltage.

When the zener diode is reverse-biased, the electric field created by the applied voltage causes electrons to flow from the valence band to the conduction band. These electrons then recombine with holes and create a narrow depletion region. When the applied voltage reaches the breakdown voltage Vz, the narrow depletion region widens, allowing the free movement of electrons, creating a large current flowing from the anode to the cathode. This current is limited by an external circuit, thus regulating the output voltage.

Conclusion

The BZV55-C36,115 is a single zener diode used for a variety of voltage regulation applications. Its reverse breakdown voltage is significantly higher than that of a normal diode and is always constant. When the applied voltage reaches the breakdown voltage Vz, a large current is created which is limited by the external circuit, and thereby regulates the output voltage. This makes it suitable for a wide range of voltage regulator and protection applications.
