Transient Voltage Suppressers (TVS) are electronic components designed to protect other circuit components from damages caused by surges in current or voltage. TVS diodes are one type of TVS, which are also known as surge protection diodes. An example of a TVS diode is the MXRT100KP54CA, which is an axial-leaded silicon avalanche diode. This diode is useful for applications that are subject to transient overvoltages, such as over-the-air broadcast or satellite reception.

Application Field of MXRT100KP54CA

The MXRT100KP54CA is designed to provide protection from transients in the power, data, and signal lines of systems that are subject to overvoltage conditions. Examples of such systems are over-the-air broadcast or satellite reception, automotive electronics, portable electronic devices such as cellular phones, and medical devices. This diode is able to protect such systems from transients by clamping close-in, low-level transients at the component and module level.

Working Principle of MXRT100KP54CA

The working principle of the MXRT100KP54CA is based on its avalanche breakdown voltage, which is low enough to be considered as a Zener voltage. When overvoltage is applied to the diode, it triggers a conducting avalanche in the diode which reduces the voltage across the diode to a safe level. The avalanche breakdown voltage of the MXRT100KP54CA is 8.2 V, with a minimum breakdown current of 3 mA.

In addition to its avalanche breakdown voltage, the MXRT100KP54CA also has a forward surge capability of up to 600 amps for 8/20 microseconds. This high surge capability helps to protect the system from potentially damaging overcurrent surges.

The MXRT100KP54CA also provides voltage protection up to 2000 volts. This helps to ensure that the diode does not break down when exposed to higher levels of voltage.

Conclusion

The MXRT100KP54CA is an axial-leaded silicon avalanche diode designed to provide transient protection for systems that are subject to overvoltage conditions. It utilizes its avalanche breakdown voltage to protect the system from low level transients, and its forward surge capability to protect the system from overcurrent surges. Finally, its 2000-volt protection helps to ensure that it does not break down under higher-voltage conditions.
