TVS diodes are an important component of any kind of device that consists of a Printed Circuit Board (PCB). They are the tiny semiconductor devices that are designed to protect a given circuit from high voltage spikes or surges. In this article, we will be discussing the application field and working principle of one particular type, 5KASMC18AHM3/9A.

The 5KASMC18AHM3/9A is generally applied in telecommunication systems and in devices that operate in hazardous industrial settings. This type of TVS diode is manufactured with a very fast response to surges or spike that last for a very short duration. It is also capable of handling up to 5kA (5 kiloamp) surge currents, allowing it to provide reliable and effective protection for electronic devices. It is also suitable for the protection of data lines such as USB and lightning connectors. The 5KASMC18AHM3/9A can also be used in power supplies, motors, electrical control systems, and even in lightning protection.

The working principle of this TVS diode is relatively simple. It works by providing a conduction path between the two terminals when a voltage spike happens. When the voltage spike occurs, it triggers the built-in diode bridge, thereby allowing the current to flow directly through the device to the other end. This current then provides a temporary surge protection by limiting the amount of voltage present. The device also has a reverse breakdown voltage of 18 Volts which protects it from further damage.

This device is also capable of limiting the voltage up to the breakdown voltage. This is done by reducing the voltage drop across its intrinsic diode, thereby preventing over-voltage. When the voltage reaches the breakdown voltage, the “on-state” of the diode starts. Afterward, the current is limited to a safe level and the device is reset by allowing the voltage to be lowered again. This helps to protect against further damage caused by the voltage spike.

The 5KASMC18AHM3/9A diode is a very reliable and effective device for the protection of electronic components. Its low capacitance and fast response to voltage spikes makes it an ideal choice for devices that operate in industrial or hazardous settings. Its low breakdown voltage also ensures that its protection capabilities are not compromised. Thus, it is a very popular choice among manufacturers of industrial and telecommunication equipment.
