TVS - Diodes

TVS, or transient voltage suppression, diodes provide protection for sensitive electronic optics and other valuable components from damaging electrical power surges. Overvoltage transient spikes are events that can occur in large amounts of electrical-powered systems, from cars to computers, and TVS diodes help protect these systems from the damaging effects of these events. The particular device, the MXRT100KP300AE3, is one of a wide range of available TVS diodes specifically designed and created to address such a particular kind of overvoltage spike.

MXRT100KP300AE3 Application Field and Working Principle

The MXRT100KP300AE3 is designed and created to provide protection against overvoltage transients in a variety of applications such as Data Com, Telecommunications, Automotive, and Industrial Equipment. It is a bi-directional TVS, designed to be automated functional element in powering protection, and uses an avalanche-trigger voltage of 11.5V. Its main features include a maximum clamping voltage of 30V, a peak pulse power of 30W, and a low leakage current of 0.1mA.

A TVS diode works by clamping a voltage spike or surge to a maximum voltage value, thus protecting vulnerable components. This is achieved with the TVS diode acting as a pair of diodes connected back-to-back. That is, the cathode of one diode is connected to the anode of another. During normal operation, the TVS diode is reverse biased, meaning no current flows between the diodes. However, when the applied voltage surpasses a certain breakdown voltage of the diodes, the diode will enter breakdown mode and current will start to flow between the diodes. This will essentially limit the voltage applied to the vulnerable component.

The MXRT100KP300AE3 works in the same way as a standard TVS diode, but with the additional feature of a ZD (Zener diode) protection. A ZD is a diode that is specifically designed to provide specific breakdown voltages. The MXRT100KP300AE3 has a ZD protection of 11.5V, meaning that once the voltage exceeds 11.5V, the ZD will start conducting current, allowing the voltage to be clamped at the specific voltage, providing protection to vulnerable components. This ZD protection ensures that any voltage surges can be effectively clamped and protected against.

In addition to providing overvoltage protection, the MXRT100KP300AE3 also provides ESD protection, or electrostatic discharge protection. This is a specific type of electrical energy that can cause serious damage to vulnerable components and can be caused by a variety of sources such as friction, movements, or even the environment. The MXRT100KP300AE3 offers ESD protection of up to 8kV, meaning it can effectively protect components from electrostatic discharges.

Overall, the MXRT100KP300AE3 is a powerful and effective TVS diode designed to provide device-level protection for diverse applications. Its bi-directional feature means it can protect a circuit from both positive and negative transients, and its ZD protection ensures effective voltage clamping. Additionally, its ESD protection ensures that components are protected from electrostatic discharges up to 8kV. The MXRT100KP300AE3 is an exciting new device that provides high-level protection for a variety of applications.
