TVS - Diodes: SMBJ7.0A-TP application field and working principle

TVS diodes are important components that can control, limit or suppress transient voltage, and their excellent performance makes them widely used in various electronic products.

Today, we will mainly introduce SMBJ7.0A-TP. This is an unidirectional TVS diode, and it belongs to the SMBJ series of television resistor products offered by the company. It has many applications for both reverse and overvoltage protection.

The device includes two diodes connected in series. This provides a high peak power, which is also very robust, and can work reliably in all environments. The package has an SMA connector with a 7.0V reverse breakdown voltage (VRWM) and an 8.0A peak pulse current (IPP).

Applications of SMBJ7.0A-TP

SMBJ7.0A-TP can be used for a range of applications, particularly for the various connector types found in the telecommunications equipment, as well as data and communications networks. It can also be used for military and aerospace applications, and applications such as wireless base stations, DSL modems, electronic drivers, and power supplies.

Given its advanced features, SMBJ7.0A-TP can also be employed in more complex applications, such as multi-voltage logic networks, as an alternative to using discrete components, providing reliable protection and a smaller footprint.

How SMBJ7.0A-TP Works

SMBJ7.0A-TP is an unidirectional device that works by blocking any current that flows in reverse. Its basic working principle can be illustrated by a simple analogy. Imagine that a diode is a one-way valve that only allows water to flow in one direction.

SMBJ7.0A-TP is the same, except it allows electric current to flow in only one direction. When forward voltage is applied across it, it conducts current and operates like a short circuit. When reverse voltage is applied, it blocks any current that flows in that direction, and acts like an open circuit.

The diode can be applied to different voltage levels to accommodate a variety of devices, from logic level circuitry to high-voltage components. The maximum voltage it can be used for is not limited, as long as it does not exceed the maximum breakdown voltage (VRWM) specified in the product specification.

Conclusion

SMBJ7.0A-TP is a robust and reliable TVS diode with a wide range of applications. Its unidirectional design ensures that it can reliably suppress transient voltage, protecting sensitive electronic equipment from damaging overvoltage and reverse polarities. Thanks to its simple design, it is also easy to use and can be applied to different voltage levels.
