TVS-Diodes, also known as Transient Voltage Suppression Diodes, are solid-state components manufactured to protect electrical systems and circuits against electrical power disruptions. They limit the amount of voltage, current, and energy that can pass during an electrical surge. In such cases, they act as a high-speed switch by allowing the power to flow through them and preventing further damage. A common type of TVS-Diode is the SMBJ64A.

The SMBJ64A is designed to protect circuits from transients with spike voltages up to 63V and pulse power dissipation up to 600W. It offers superior suppression in a wide variety of applications including telecommunications, computers, automobiles, energy systems, and telecommunications. It is capable of withstanding surge energy up to 5A. The SMBJ64A works by clamping the voltage at the maximum peak value, allowing low-level signals to pass through without interruption or distortion. This ensures that the circuit remains intact during a surge.

The SMBJ64A device has a multitude of applications. It is most commonly used in power supplies and power converters, to protect components from transient spikes. It offers suppression of spikes caused by static electricity, lightning strikes, and ESD (electrostatic discharge). This device is also used in computer motherboards, surge suppressors, voltage supplies, and other electronic components. Its superior quality and performance make it the ideal choice for these types of applications.

The working principle of the SMBJ64A is simple. When the input voltage reaches the peak value, the device acts as a switch closing the current path, allowing the surge current to pass and the voltage to be clamped at the maximum peak value. Current passing through the device is limited, and then decreases as the input voltage decreases. This ensures that the components in the circuit are not damaged. After the peak voltage has been reduced, the device will reset and the circuit will be back to its original state.

The SMBJ64A is an efficient, reliable, and robust device that provides superior protection for a wide variety of electrical systems. Its fast response time and high suppression level make it the ideal choice for applications that require protection from electrical power disruptions. The device is easy to install and use, ensuring that it can be implemented in any system with minimal effort.
