The SMAJ170CE3/TR13 TVS diode is an effective solution for protecting against electrical transients caused by electrostatic discharge, induced lightning, power cross and other voltage-induced surge events. It can be used in a variety of application fields and will provide excellent protection to sensitive electronic components. In this section, we will take a look at the application field and the working principle of the SMAJ170CE3/TR13.

The application field of the SMAJ170CE3/TR13 is mainly concentrated in portable electronics, such as smartphones, tablets ,netbooks and other devices. This TVS diode is suitable for protecting all kinds of consumer electronic products due to its fast response time and low capacitive coupling. It is capable of protecting all kinds of circuits and components from voltage-induced transients such as electrostatic discharge (ESD), induced lightning, power cross surge and other surge events.

The working principle of a TVS diode is fairly straightforward. The device consists of two main components: a diode and a varistor. When the device sees a surge event, the diode quickly conducts, allowing current to flow through the TVS diode from the source to the load. The varistor reduces the voltage of the surge, protecting the components. The device can handle both AC and DC voltage levels, ensuring the safety of the components they are protecting.

The SMAJ170CE3/TR13 is built to meet the strict specifications of IEC 61000-4-2 standard for ESD immunity, meaning it is suitable for use in both indoor and outdoor environments. The device is rated for up to 15kV for air discharges and 8kV for contact discharges. It also features a very fast response time of less than 1µs, allowing it to effectively protect sensitive components from voltage-induced transients. Additionally, it has low capacitive coupling, meaning it can be used in high-frequency applications as well.

In summary, the SMAJ170CE3/TR13 performs a vital role in protecting sensitive electronic components from electrical transients. It is suitable for protecting portable electronics such as smartphones, tablets, and netbooks, as well as other consumer electronics. It features a fast response time of less than 1µs, and it is rated for up to 15kV of air discharge and 8kV of contact discharge. Additionally, it has low capacitive coupling, making it suitable for high-frequency applications as well.
