TVS - Diodes

Transient Voltage Suppressor (TVS) diodes exist to protect sensitive electronic equipment from voltage spikes such as inductive kickbacks and electrostatic discharge (ESD). SMA5J9.0C-E3/5A is an example of such a device. This article describes the application field and working principle of this device.

SMA5J9.0C-E3/5A is a unidirectional silicon TVS diode that is designed specifically for protecting high-speed interfaces in digital consumer electronics, notebook computers, and other connected devices. This device has a reverse working voltage of 9.0V, reverse stand-off voltage of 5.0V, and a power dissipation rating of 5.0A. In addition, the device offers excellent ESD protection and is RoHS compliant, making it an ideal solution for these kinds of applications.

The working principle of SMA5J9.0C-E3/5A is based on a Zener breakdown effect. When the reverse voltage exceeds the Zener breakdown voltage of the diode, a rapid depletion layer forms which rapidly reduces the potential barrier, allowing the diode to conduct the current. The main advantage of this device is that it can quickly absorb large amounts of energy and dissipate it safely. This helps protect other components from being damaged due to the voltage spike.

In addition to ESD protection, SMA5J9.0C-E3/5A can also be used in other applications such as surge protection and power line noise filtering. As a surge protector, the device is able to absorb the surge energy and protect other components from damage. As a power line noise filter, the device is able to reduce noise in the power line, improving the performance and reliability of the system.

In summary, SMA5J9.0C-E3/5A is an effective and cost-effective solution for protecting high-speed interfaces in digital consumer electronics, notebook computers, and other connected devices. The device has a reverse working voltage of 9.0V, reverse stand-off voltage of 5.0V, and a power dissipation rating of 5.0A, making it an ideal solution for these types of applications. Furthermore, the device offers excellent ESD protection and is RoHS compliant, making it the ideal solution for both surge protection and power line noise filtering.
