TVS - Diodes

TVS – Diodes provide a static, nonlinear resistance to the flow of electricity. These diodes are used in applications where transient overvoltage spikes or energy pulses need to be suppressed. The type of diode used in these applications is usually either the Zener or the avalanche diode.

BZW04-5V8HR0G application and working principle

The BZW04-5V8HR0G is a single line TVS diode that dissipates ESD protection pulses of up to 8KV. It is used for data interfaces and also for transient voltage protection. The BZW04-5V8HR0G operates through a breakdown mechanism, or avalanche. In this process, the diode is subjected to an over-voltage and a current begins to flow through the diode. This process causes an avalanche of electrons and holes through the PN junction of the diode, and the breakdown voltage of the device is reached.

The BZW04-5V8HR0G also has a low capacitance of 1.2 pF, as it is essential for some high-speed communication applications. The temperature coefficients and working voltage are also well-defined, making it useful for a variety of applications. Furthermore, because it is a single line diode, it is suitable for both unipolar and bidirectional overvoltage protection.

The low-clamping voltage of the BZW04-5V8HR0G make it suitable for applications where the line voltage must be limited. This device is able to reduce the voltage amplitude for overcurrents, spikes, and other high-voltage events. Furthermore, it also provides the necessary protection from transient electrical events.

Conclusion

In conclusion, the BZW04-5V8HR0G is an ideal choice for transient voltage spike and ESD protection. It is a single line device that offers low capacitance, temperature coefficients, and working voltage. This makes it well-suited for a wide variety of applications, and provides the necessary overvoltage protection.
