Transient voltage suppressors (TVS), also known as varistors or surge suppressors, are devices which are used to protect electrical components from high voltage spikes. TVS diodes are a type of voltage-regulating device, and the MXRT100KP120A is a model of TVS diode from the company Microchip. In this article, we will look at the application field of the MXRT100KP120A and its working principle.

Application Field

Due to its design and construction, the MXRT100KP120A is an ideal choice for applications that require protection from extremely high voltage spikes. It is primarily designed to protect circuits and components from voltage spikes in automotive electrical systems, and it is very common in automotive applications such as audio systems, lighting and signal circuits. The device can also be used to protect various electrical components in many different industrial and consumer applications.

The MXRT100KP120A provides reliable and effective ESD protection, and it is available in a variety of different package types for a wide range of applications. The device is available in a 1206 surface mount package, which is easy to assemble and mount in a PCB. The device also has built-in safeguards against reverse voltage and short-circuit protection, which ensures that the device operates reliably in all conditions.

Working Principle

The MXRT100KP120A is a bidirectional TVS diode, which means that it can withstand high voltage spikes both in the forward and reverse directions. The device fundamentally works like a regular diode, in that it allows current to flow in one direction, while blocking it in the other. However, this diode also has what is known as a “clamping voltage,” which is the voltage at which the diode will start to limit or clamp the current. This clamping voltage is usually adjustable by means of an external resistor, making the device highly versatile and suitable for a range of applications.

When the voltage across the device is lower than the clamping voltage, the diode will operate in its forward direction, allowing current to flow through the device. However, if the voltage across the device exceeds the clamping voltage, the diode will start to limit or clamp the voltage, preventing the voltage from reaching unsafe levels. This is how the device protects other components from the effects of high voltage spikes.

The MXRT100KP120A is a highly reliable and effective TVS diode which is suitable for a variety of different applications. It is designed for use in automotive applications, and it provides reliable protection for circuits and components from high voltage spikes. It is also very easy to use, as it has adjustable clamping voltage and built-in safeguards against reverse voltage and short-circuit protection.
