TVS (Transient Voltage Suppressor) diodes, also known as varistors (variable resistors), are often used to protect circuits from over-voltage surges, which can occur under certain conditions. The SA160A-E3/54 is one such device, capable of handling transients up to 55V. It can be used in a range of applications, including automotive, consumer electronics, industrial control, telecommunications and computing. This article will provide an overview of the device’s application field and working principle.

Applications

The SA160A-E3/54 is a highly versatile TVS diode that can be used in a variety of applications, including automotive, consumer electronics, industrial control, telecommunications and computing. In automotive applications, it is used as an over-voltage protection device to protect circuits from short-circuit transients. In consumer electronics, it is used to protect computers, game consoles, mobile devices and other electronics from power fluctuations. It is also used in industrial control systems, where it can protect sensitive components from surges and over-voltage transients. In telecommunications, it is used to protect against over-voltage surges caused by lightning strikes. Finally, it can be used in computing to protect motherboards, processors and other components from power surges.

The SA160A-E3/54 is ideal for applications that require high peak power handling capabilities. It has an ultra-fast response time of 1.5ns, which means it can react quickly to over-voltage transients, providing superior protection. It is also able to handle high reverse power up to 55V, making it suitable for use in higher voltage systems. Furthermore, the device is RoHS compliant and is available in a small, low profile SOD-123 package, meaning it can easily be integrated into any space-constrained system.

Working Principle

Like all TVS Diodes, the SA160A-E3/54 is a semiconductor diode that is designed to protect circuits from over-voltage transients. When an over-voltage surge occurs, the diode becomes “forward biased,”, meaning that current from the surge is allowed to flow through the device. As current flows, it is dissipated as heat, protecting the circuit from damage. The device is designed to absorb a large amount of power in a very short period of time, and then quickly recover once the surge has passed.

The SA160A-E3/54 has an operating range of 5~55V, meaning it can protect circuits from transients ranging from 5V to 55V. It also comes with a low capacitance of 0.75pF, ensuring that EMI/EMC susceptibility is kept to a minimum. Finally, the device is capable of operating up to +150°C, making it suitable for use in high temperature environments.

Conclusion

The SA160A-E3/54 is a highly versatile and reliable TVS diode, capable of handling transients up to 55V. It can be used in a range of applications, including automotive, consumer electronics, industrial control, telecommunications and computing. The device has a fast response time of 1.5ns and is able to handle high reverse power up to 55V, making it suitable for use in higher voltage systems. Furthermore, the device is RoHS compliant and is available in a small, low profile SOD-123 package, making it easy to integrate into any space-constrained system.
