Transient Voltage Suppressors (TVS) are used to protect electrical devices from high transient voltage levels. TVS diodes are the most commonly used type of TVS, they are equipped with a high peak current handling capability, fast response time, and are relatively inexpensive. In this article, we will discuss the application field and working principle of a SMDA05.T TVS diode.

Application Field

SMDA05.T TVS diodes are used in a variety of applications, from automotive, communications and consumer electronics to industrial, medical, and military applications. SMDA05.T diodes are well suited for applications that require high peak current handling capability, low leakage current, and high reliability. For example, they are used to protect vehicle circuit boards from transient voltage levels due to shunts and slip rings, as well as for providing over-voltage protection for communication circuits. Additionally, they can also be used as an internal protection device in portable electronic products, such as mobile phones and MP3 players.

Working Principle

SMDA05.T TVS diodes are designed to protect electronic devices from over-voltage and surge events. The diode is constructed in a p-n junction, which is capable of conducting only in one direction. When an over-voltage or surge event is detected, the p-n junction of the diode becomes forward biased, allowing current to flow through the diode. The current is then dissipated through a low resistor within the diode, effectively dissipating the over-voltage or surge event. After the transient voltage has been dissipated, the diode returns to its blocking state, preventing further current flow.

Conclusion

SMDA05.T TVS diodes are a reliable and cost-effective solution for protecting electronic circuits from transient voltage levels. The diode is capable of handling high peak currents and has a fast response time, making it suitable for a wide variety of applications. Additionally, the device is designed to offer improved performance and reliability in hostile environments.
