Transient Voltage Suppressors (TVSs) diodes are devices used to protect electrical systems from damaging voltage transients. BZW04-239B-E3/54 is a TVS diode that is designed to protect equipment against over-voltage transients.

Application Field

The BZW04-239B-E3/54 TVS diode is designed to protect electrical systems from high voltage surges, spikes, and over-voltages. It has a very low forward voltage drop and a wide operating temperature range, making it suitable for use in a variety of electrical and electronic applications, such as automotive, communications and network protection, computer and peripheral protection, as well as industrial and consumer electronics.

The BZW04-239B-E3/54 is suitable for use in high-voltage, high-current applications, such as automotive engines, remote control systems, power supplies, and solar inverters. It can also be used to protect a data line from over-voltage transients, and is suitable for use in harsh environments where a significant amount of over-voltage may be present.

Working Principle

The BZW04-239B-E3/54 is a bidirectional TVS diode that uses avalanche breakdown, which is the sudden release of energy that occurs when a large electric field is applied across a diode junction. When a voltage transient higher than the diode\'s avalanche breakdown voltage is applied, the diode will conduct the current and thereby limit the voltage across the protected component, protecting it from damage due to over-voltage transients.

The diode also has a very low forward voltage drop, meaning that it will only require a minimal amount of current to operate properly. The low forward voltage drop is especially important in high-current applications, where it can help to minimize power losses due to wasted energy.

The BZW04-239B-E3/54 is designed for use in high-voltage, high-surge applications, and it is configured with an internal protection circuit that prevents damage due to over-currents and protects the diode from damage due to other electrical faults. Joint Electron Device Engineering Council (JEDEC) standards are followed when designing the internal protection circuit.

The BZW04-239B-E3/54 features a wide operating temperature range, and is designed to operate between -55°C and 150°C. This wide temperature range allows the diode to be used in a variety of applications where the temperatures may be extreme. The diode is also protected against electrostatic discharge (ESD) up to 25kV, making it suitable for use in high-voltage environments.

Conclusion

The BZW04-239B-E3/54 is a TVS diode designed to protect electrical systems from over-voltage transients. The device is suitable for use in high-voltage, high-current applications, and features a low forward voltage drop, a wide operating temperature range, and protection against electrostatic discharge.
