TVS - Diodes: BZA868A,115 Application Field and Working Principle

TVS (Transient Voltage Suppressor) diodes are special types of diodes that provide protection against lightning strikes, power surges, and other forms of high-voltage, high-energy events. They are used to protect electronic equipment from excessive voltage, transients, and other potentially damaging events. The BZA868A,115 is one such TVS diode, which is a popular choice for transient protection.

Applications

The BZA868A,115 is a unidirectional TVS diode, meaning it can only function in one direction. It is often used in automotive and industrial applications to protect circuits and components from transient voltage spikes caused by lightning, electronic switching devices, and other high-voltage events. These diodes are usually found in power supplies, industrial systems, automotive electronics, and other devices where protection from transients is needed.

Features

The BZA868A,115 has a breakdown voltage of 8V, a maximum surge current of 115 A, and a clamping voltage of 11.5V. It is designed to provide protection against voltage transients up to 1500 VDC. The device has a low capacitance and an extremely fast response time, making it a great choice for protecting sensitive electronics. Additionally, the BZA868A,115 has a wide operating temperature range and is RoHS compliant.

Working Principle

When a voltage transient occurs, the BZA868A,115 will be triggered and start to conduct current. This current will be limited to a maximum of 115 amps, as that is the maximum surge rating for this device. The current is then dissipated harmlessly, preventing any damage to the system. In addition, the diode\'s clamping voltage will rise to a maximum of 11.5V, which ensures that the voltage spike does not exceed this level.

Conclusion

TVS diodes such as the BZA868A,115 are essential components in ensuring the safety of electronic systems. They are well-suited for protecting circuits and components from high-voltage, high-energy events, such as lightning, power surges, and other transients. The device has a low capacitance, fast response, and a wide operating temperature range, making it a great choice for transient protection. With its maximum surge rating of 115 amps and a clamping voltage of 11.5V, the BZA868A,115 is a reliable and effective protection solution.
