TBZ363C6V4-7-F TVS - Diodes Application Field and Working Principle

TVS (Transient Voltage Suppression) Diodes, also known as Transient Voltage Surge Suppressors, have been used in various applications for many years as a reliable protection device to safeguard connected electrical and electronic components. The TBZ363C6V4-7-F, as a member of the TVS - Diodes family, is mainly used in the automotive, industrial, consumer and medical applications.

The TBZ363C6V4-7-F is a unidirectional diode with minimum capacitance and very fast clamping response. It offers superior surge suppression performance to protect sensitive components with very low clamping voltage directly connected to the device. With its low capacitance, low forward voltage and very high surge current capability, the TBZ363C6V4-7-F can protect up to 4 kW peak pulse power withstanding voltage up to 6 V.

The TBZ363C6V4-7-F is designed to protect against the surge overvoltage generated from electrostatic discharge (ESD), lightning and switching transients, which can affect signal and data lines, computer interfaces, handheld and portable electronics, automotive systems, medical instruments and industrial processes. As required, the TBZ363C6V4-7-F is IEC 61000-4-2 (ESD) Compliant.

Working Principle of a TVS Diode

TVS Diodes are essentially spark gap devices that provide a low resistance path when a certain voltage level is exceeded. As with any diode, the TBZ363C6V4-7-F has two terminals, an anode and a cathode. When the applied voltage is below its reversible breakdown voltage, no current flows through the device. Once the breakdown voltage is exceeded, current flows through the device and the diode starts to conduct. This is referred to as the clamping voltage.

When properly connected, the TBZ363C6V4-7-F will transfer the surge current, without the impedance of the associated system circuitry, to a safe ground potential. The stored energy from the current surge is then dissipated as heat. Thus, the main purpose of a TVS Diode is to protect downstream components from overvoltage and transients.

Applications of TBZ363C6V4-7-F

The TBZ363C6V4-7-F can be used in a range of applications that call for comprehensive surge protection. It can be applied in a variety of automotive, industrial, consumer and medical applications, including but not limited to: automotive safety systems, radar systems, mobile phones, satellite communications, and medical diagnostic and treatment equipment.

The TBZ363C6V4-7-F is also often used in lighting systems and elevator applications, providing robust support for the drive circuits. The device can also be used in industrial automation systems to protect internal wiring and data lines from ESD and transient voltage spikes.

Conclusion

TBZ363C6V4-7-F TVS - Diodes are ideally suited for applications that require protection from surge and transient overvoltages induced by ESD, lightning, and switching transients, since it has a low capacitance, low forward voltage, and a very high surge current capability.

The device is well-suited for use in automotive, industrial, consumer and medical applications, providing superior surge protection for sensitive components with very low clamping voltage. The device is also compliant with the IEC 61000-4-2 ESD standard, making it an excellent choice for any application that requires robust static surge protection.
