Transient voltage suppressors (TVS) are electrical components that are designed to protect sensitive electronic devices from damage due to voltage spikes and power surges. They are capable of clamping excessive voltages and dissipating excess current safely. The MXRT100KP250CA is a robust and reliable TVS diode that is used in many applications. This article will discuss the application field and working principle of the MXRT100KP250CA.

The MXRT100KP250CA is a multi-layer avalanche diode that is capable of withstanding surge currents up to 5kA (8/20 microseconds). It is also capable of suppressing voltage levels up to 5V. This makes it ideal for use in applications such as automotive, industrial, lighting, communications, consumer, and ITE equipment. The device is rated for operation at up to 250Vrms and will clamp at 250V with a maximum clamping voltage of 350V.

The main advantage of TVS diodes such as the MXRT100KP250CA is their ability to shunt excessive voltages to ground while limiting the current to a safe level. The voltage-limiting process begins with a sharp rise in voltage, which activates the avalanche breakdown. The breakdown triggers the triggering mechanism of the diode, allowing the current to flow in the reverse direction. The excess current is then diverted to ground, thereby limiting the voltage to a safe level.

In order to better understand how the MXRT100KP250CA works, it is important to understand the concept of avalanche breakdown. When an electric field is applied across a diode such as the MXRT100KP250CA, electrons in the PN junction region will be accelerated, resulting in a rapid increase in the current. As the current increases, the temperature of the junction region will also rise, resulting in a further increase in current. Eventually, the thermal instability will cause the diode to reach a breakdown voltage, at which point the current will be allowed to flow in the reverse direction. This reverse current flow is then diverted to ground, effectively limiting the voltage across the diode and protecting the components from damage.

The MXRT100KP250CA is a reliable TVS diode designed to provide protection to sensitive electronic components in a variety of applications. Its multi-layer construction and voltage limiting capabilities make it an ideal choice for automotive, industrial, lighting, communications, consumer, and ITE applications. Its unique avalanche breakdown mechanism allows the device to clamp excessive voltages and divert excess current to ground, thereby protecting sensitive components from damage. With its robust design and versatile capabilities, the MXRT100KP250CA is well-suited for a wide range of safety applications.
