Its design is largely unaffected by clamps or other feedback signals, meaning it is well-suited for use in automotive applications.

Working Principle

The BZW04-5V8BHE3/54 uses reversed polarity avalanche diode technology to protect components from harm. Its internal structure consists of multiple layers of diodes and is designed to provide a robust layer of protection against high-frequency transients. Its essential role is to limit electrolytic capacitors and other vulnerable components from harm.

When an overvoltage transient occurs, the BZW04-5V8BHE3/54 quickly absorbs the electrical energy and dissipates it as heat. This forward bias of the Avalanche diode prevents the overvoltage transients from reaching the component, effectively providing protection against overloads and transient voltage suppression. The device is designed to clamp fast transients with low overshoot or no overshoot, allowing it to handle high-energy spikes while efficiently protecting its connected components.

The BZW04-5V8BHE3/54 also includes integrated EMI filtering, designed to reduce the EMI interference generated by high frequency harmonics that may occur in circuits. This filtering helps improve the EMC performance of components to comply with legal requirements, while increasing the overall performance and stability of the system.

Summary

The BZW04-5V8BHE3/54 is a reliable transient voltage suppression diode, suitable for a variety of applications. It is designed to provide protection from voltage transients, overloads, and other electrical issues in order to ensure the safety of components, systems and equipment. The device is well-suited for household, automotive and industrial applications due to its robust and reliable design. It is also widely used for EMI/RFI filtering to reduce electrical interference and ensure that systems remain compliant with legal requirements.
