SMBG14CAHE3/52 is a kind of transient voltage suppressor (TVS) diode, which can quickly limit the voltage spike in an electronics circuit, thus protecting downstream electronic components from damage caused by high voltage spikes. TVS diode is a crucial part of electronic protection design in many industries. Its application field and working principle will be discussed in this article.

Application Field

The SMBG14CAHE3/52 is intended for a whole range of applications to protect electronic components from high voltage surges in both AC and DC environments. Because of its low leakage current, it provides excellent protection for communication circuits. This diode is also widely used to protect devices from lightning strikes, electrostatic discharge and power surges in automobiles, military applications, consumer electronics, and other industries.

The SMBG14CAHE3/52 offers excellent surge protection performance in a small package size. Its RoHS compliant, making it suitable for applications in hazardous locations. Also, this diode is compatible with a variety of electric and automotive systems, including cars and trucks. It can even be used in aerospace applications.

Working Principle

The SMBG14CAHE3/52 is a bi-directional diode, which means it can limit voltage spikes in both directions. When a voltage spike above its breakdown voltage occurs, the diode will quickly conduct the surge current and then become forward biased. This will limit the overvoltage and offer protection for the downstream components.

The diode is designed to dissipate high levels of energy. This is achieved through its large surge capability and fast response time. It has a maximum reverse standoff voltage, which is the voltage at which the diode will begin to limit overvoltage, of up to 14V. And its maximum peak pulse power can handle up to 52W.

In addition, the SMBG14CAHE3/52 offers thermal stability and reliability against extreme temperatures. It is able to withstand up to 125°C without degradation. This means it can be used in harsh environments without worrying about it failing.

Conclusion

The SMBG14CAHE3/52 diode is a TVS diode designed to protect electronic components from high voltage spikes. It offers excellent protection and thermal stability in a variety of applications, including automobiles, communication circuits, aerospace, and more. It has a low leakage current, maximum reverse standoff voltage of up to 14V, and maximum peak pulse power of 52W. With all these features, the SMBG14CAHE3/52 is a great choice for providing reliable protection for electronic components in extreme environments.
