Transient Voltage Suppressors (TVS) are devices that protect sensitive electronics from voltage spikes and are used for applications such as EMI/RFI filtering, voltage clamping and over-voltage protection. The Field Effect Transistors (FET) series of TVS, such as the MXP4KE22CA, is amongst the most popular and is used in a wide variety of electronic circuits such as analog, digital and mixed-signal circuits. This article discusses the application fields and working principle of the MXP4KE22CA.

The MXP4KE22CA is a three-terminal FET TVS that is designed to protect components against voltage surges up to 20 V. It is designed with a built-in ESD protection, reverse bias protection and steer diodes, making it suitable for applications requiring protection from high-voltage spikes, over-voltage and EMI/RFI noise. The MXP4KE22CA can also be used in circuits for high-speed data transmissions due to its excellent response time of less than 1.0 ns. It is also able to withstand voltages up to +250V while maintaining low capacitance.

In terms of its application fields, the MXP4KE22CA is commonly used in circuits that are sensitive to high voltages, such as power supplies, voltage regulators, motor controls, logic circuits and LCD/LED displays. In these types of circuits, the MXP4KE22CA can help to ensure reliable operation and protection of the components from voltage surges. Additionally, the MXP4KE22CA is often used in automotive electronics applications, such as in airbag systems, to provide reliable protection against high voltage spikes caused by a crash or electrical interference.

The working principle of the MXP4KE22CA is quite simple. When a transient voltage surge occurs, the voltage is clamped to the MXP4KE22CA’s breakdown voltage. The breakdown voltage is the voltage at which the device starts conducting current. This clamps the voltage and protects the sensitive components from being damaged from the surge. Additionally, the MXP4KE22CA is reverse bias protected, which means that if reverse voltage is applied to the device, it will stay in the off state and prevent any damage.

In conclusion, the MXP4KE22CA is a versatile and reliable FET transient voltage suppressor that can provide excellent protection from voltage surges, over-voltage, EMI/RFI noise and reverse voltage. It is suitable for use in a variety of sensitive applications, such as power supplies, logic circuits and LCD/LED displays. Its working principle is based upon clamping the voltage to its breakdown voltage when a transient voltage surge occurs. As an added benefit, it also features built-in protection against reverse voltage.
