The TVS-Diodes are considered as a reliable form of surge protection and are becoming increasingly popular due to their robustness and ease of use. The SMAJ85CA-13-F is one such device, designed to provide a reliable surge protection solution. This article explores the application field and working principle of SMAJ85CA-13-F.

Application Field of SMAJ85CA-13-F

One of the most common application fields of the SMAJ85CA-13-F is in automotive electronics. Automotive electronics are required to withstand high levels of shock and vibration, and the SMAJ85CA-13-F is suitable for use in such applications. It can be used to protect vehicle wiring, batteries, and other electronic components from a potentially damaging voltage spikes. This surge protection device can also be used in other applications, such as industrial, electrical, and consumer electronics.

Working Principle of SMAJ85CA-13-F

The SMAJ85CA-13-F is an integrated ultra-low capacitance transient voltage suppressor (TVS) device. This device, like most TVS-diodes, works by utilizing a combination of voltage and capacitance to suppress voltage spikes. When a voltage spike occurs, the device begins to rapidly discharge its energy and absorb the excess voltage. The SMAJ85CA-13-F can be connected in series with a power line or other sensitive electronic components for protection against sudden electrical surges.

The SMAJ85CA-13-F provides two separate protection levels for enhanced safety. The first protection level includes an overvoltage protection function which is designed to limit the peak voltage to a set value. The second protection level is an active clamp function, which is designed to further reduce the voltage surge through the use of Zener diodes. This active clamp function ensures that the parts connected to the SMAJ85CA-13-F are not damaged by sudden electrical surges.

In addition to providing protection against voltage surges, the SMAJ85CA-13-F also ensures that the connected parts are not exposed to excessive noise, and it provides short circuit protection. The device also has a low capacitance design, which maximizes signal integrity and ensures a low voltage drop across the TVS.

Conclusion

The SMAJ85CA-13-F is a reliable and user-friendly TVS device, providing a robust surge protection solution in a wide range of electronic applications. The device is designed to provide two levels of protection against voltage surges, as well as short circuit protection and minimal signal degradation. By utilizing this device, users can protect their sensitive electronic components against damaging voltage surges.
