TVS (Transient Voltage Suppressor) diodes are commonly used in electronics for providing protection against the damaging effects of short duration transient voltage spikes. The BZW04-28B R0G is a specialized form of these diodes with a wide range of applications and a sophisticated working principle.

The BZW04-28B R0G is a bi-directional device with a specified rated peak pulse power of 600W. It has a maximum clamping voltage of 28V and a maximum unidirectional peak pulse current of 600A. Its maximum leakage current is 0.1mA, and its capacitance is 6pf. It is a low capacitance device, making it well suited for protection of vulnerable sensitive electronic components.

The working principle behind the BZW04-28B R0G is a combination of junction capacitance and avalanche breakdown. When normal working conditions are maintained, its capacitance passes a reverse current through the diode in order to provide protection against transient voltage surges. However, when the energy of a transient voltage surge exceeds the breakdown voltage, the diode will undergo avalanche breakdown, allowing for the power to be safely discharged and thereby preventing further damage.

The BZW04-28B R0G is typically used in a wide range of consumer electronics, automotive electronics, power supplies, motor control systems and industrial applications. In consumer electronics, they are primarily used to protect the integrated circuit from transient voltage surges caused by electrostatic discharge. In automotive electronics, they are used to protect the electronics systems from transient spikes caused by voltage spikes due to changing loads on the electrical system. In power supplies and motor control systems, the BZW04-28B R0G can protect components from voltage spikes due to the current draw of the motor and other components. Lastly, in industrial applications, the BZW04-28B R0G can provide protection to sensitive processes from transient voltage surges and voltage spikes.

In conclusion, the BZW04-28B R0G is an indispensable component in today’s electronics and provides reliable protection against transient surges. It is widely utilized in a range of industries and applications and is capable of providing robust protection against voltage spikes. Furthermore, its combination of junction capacitance and avalanche breakdown provides a versatile yet powerful mechanism for protecting vital electronics.
