Introduction
The BZV85-C43,133 is a single Zener diode from Diodes Incorporated. Zener diodes can be used to provide protection from overvoltage conditions and protect sensitive circuitry from voltage spikes or transients that may cause damage. This particular device is designed to regulate the voltage in applications up to 450V, and can operate at maximum currents up to 5A. It also contains a wide range of features such as surge rating, an operating temperature range of -55C to +150C, and a variety of package options.

Application Field
The BZV85-C43,133 is primarily used in automotive and industrial electronics, and can be employed in a variety of roles. In its most basic form, it can be used to provide overvoltage protection to sensitive electronics. This is especially useful in vehicles, which often experience transient voltage spikes due to different components being powered up or down. The BZV85-C43,133 can also be used for more complex purposes such as providing surge protection for sensitive circuitry, as well as voltage regulation for load mismatching in redudant systems. It is also used in higher voltage applications such as lighting control, where it can be used to regulate current passing through the system.

Working Principle
The working principle of the BZV85-C43,133 is relatively simple. It is an intrinsic P-N junction diode, meaning that it uses the principle of diode conduction to regulate voltage. When forward biased, this diode will begin to conduct current, allowing it to regulate the flow of current. When the voltage being supplied surpasses the Zener voltage of the diode, the reverse-biased junction begins to conduct current as well, effectively regulating the voltage and preventing spikes or transients. As the voltage exceeds the value of the Zener voltage, the reverse current increases proportionally. This allows the device to regulate the voltage, preserving the operation of the electronic component.

Performance
The BZV85-C43,133 is a robust component, and is capable of providing protection from surges and transients up to 450V. It is also able to handle large amounts of current up to 5A. It also has a peak forward and reverse current rating of 10A, allowing for a steady flow of current throughout its operating range. In addition, it also has a variety of features such as a wide operating temperature range of -55C to +150C, and a surge rating of up to 200A. All of these features make the BZV85-C43,133 ideal for a variety of industrial and automotive applications.

Conclusion
The BZV85-C43,133 from Diodes Incorporated is a single Zener diode that can provide a variety of voltage regulation and overvoltage protection solutions for industrial and automotive applications. It utilizes a P-N junction diode to regulate the flow of current through it and provide protection from transients up to 450V. It is also capable of handling large amounts of current up to 5A, with a peak forward and reverse current rating of 10A, and a wide operating temperature range of -55C to +150C, as well as a surge rating of up to 200A. All of these features make the BZV85-C43,133 an ideal device for a variety of applications.
