TVS diodes are electronic components designed to protect sensitive electronic components from voltage spikes. The SMB8J12CHE3/5B is a bidirectional Transient Voltage Suppressor (TVS) suitable for medium transient applications. This type of diode can protect electrical devices from overvoltages that might be caused by an electrostatic discharge, an inductance strike, or an electrical surge, such as those resulting from lightning.

The SMB8J12CHE3/5B has an operating voltage of 5.0V. Its working voltage ranges between 9.0V and 5.0V. In terms of current capability, the device is capable of handling up to 3A of continuous current and 5A of peak pulse current. In addition to its operating and working voltage, its clamping voltage is 17.5V. The clamping voltage is the maximum allowable voltage that can be applied to the device before it begins to conduct. The device also has an operating temperature range of -55°C - 150°C, making it suitable for a wide range of applications.

The SMB8J12CHE3/5B can be used in a variety of application fields. Its most common application is in the telecommunications industry, specifically in the protection of telephone lines from high-voltage surges that could otherwise damage components and equipment. It is also used in computers and peripherals, specifically in the protection of the internal components from harmful electrostatic fields. In addition, it can be found in automotive applications, such as in the ignition systems, charging circuits, and other vulnerable components.

In order to operate effectively, the SMB8J12CHE3/5B needs a certain voltage to be applied to it. When exposed to a voltage beyond the rated working voltage, the device will begin to conduct current. This current will flow through the device until it is dissipated as heat. The heat generated will cause the device to break down, and in some cases, it may be destroyed completely. This process is known as "clamping".

The SMB8J12CHE3/5B is a good choice for applications requiring medium transient protection from electrical over-voltage. Its wide voltage range, robust construction, and simple installation make it an attractive option for those who need effective overvoltage protection for their electrical equipment.
