Introduction

TVS (transient voltage suppressor) diodes are widely used to protect sensitive equipment from transient voltage spikes caused by lightning, electrostatic discharge (ESD), and other sources. The 1SMB8.0A TR13 is an unidirectional transient voltage suppressor diode designed for telecommunication and other applications that require very low capacitance and high/low breakdown voltage.

Application Field

The 1SMB8.0A TR13 is designed specifically to protect sensitive equipments from transient voltage spikes. It is particularly well suited for applications such as Ethernet and USB ports, data lines, and other signal line protection in computing and communication systems. It is also suitable for a wide variety of overvoltage and ESD protection in industrial, automotive, and consumer electronic applications.

Working Principle

The 1SMB8.0A TR13 is a unidirectional transient voltage suppressor diode. It works by providing a low capacitance, high/low breakdown voltage barrier to restrain overvoltages from flowing into sensitive components. When a transient voltage spike exceeds the breakdown voltage, the device acts as a short circuit across the gap, allowing the current to flow and effectively clamping the voltage. In this way, the voltage is suppressed and the transient voltage spike is safely discharged into ground.

Features

The 1SMB8.0A TR13 offers a number of features that make it well suited for transient voltage suppression and signal line protection in telecommunication and other applications. It has a very low capacitance of 0.3 pF, which helps reduce cross talk between data lines and minimizes signal distortion. The high surge rating of 600 Watts helps it withstand large surges of current, providing an extra level of protection against severe transient voltage spikes. It also has both high and low breakdown voltages, allowing it to protect against a wider range of overvoltage conditions. In addition, the device is RoHS compliant, making it a suitable choice for applications requiring the highest environmental standards.

Conclusion

The 1SMB8.0A TR13 is a unidirectional transient voltage suppressor diode optimized for telecommunication and other applications requiring very low capacitance and high/low breakdown voltage. It is designed to provide effective protection against transient voltage spikes, ESD, and other sources of overvoltage. Its features include a low capacitance of 0.3 pF, a high surge rating of 600 Watts, and both high and low breakdown voltages. In addition, the device is RoHS compliant, making it suitable for a wide variety of applications.
