This article will discuss the application fields and working principle of the SMF26A-M3-18 TVS diode.

Applications

SMF26A-M3-18 TVS diode is mainly used in data line protection. With its perfect quality and good reliability, this TVS diode can effectively control and limit the overvoltage on the data line. This is achieved through its fast clamping action. When a voltage spike appears, the diode will conduct current and keep the voltage on the data line under the preset limit. It can also be used in other practical scenarios such as overvoltage protection for automobiles, Overvoltage protection of consumer electronics, ESD protection, and so on.

Working principle

The SMF26A-M3-18 TVS diode used in data line protection is usually designed to protect circuits from transient voltage spikes. When a voltage spike appears on the data line, the diode will immediately start to conducting current and reduce the voltage to a certain predetermined voltage, thus protecting the circuit on the other side. At the same time, the diode also helps to reduce the electromagnetic interference to the circuit, which is beneficial for the signal transmission.

The series of SMF TVS diode has a working voltage range from 5V to 180V, which can provide effective protection for the line, and its superiority of ultra low capacitance allows it to maintain high signal integrity over a wide range of frequencies. In terms of surge protection capability, the SMF26A-M3-18 can withstand 10000watt surge and the corresponding ESD test maintains up to 8kV.

Conclusion

To sum up, the SMF26A-M3-18 TVS diode is a reliable protective component that can provide effective protection from overvoltage or electromagnetic interference for a variety of data lines. It has a wide working voltage range, low capacitance, and excellent surge protection capability. Therefore, it is widely used in data line protection, automotive, consumer electronics, and other fields.
