MXP4KE180AE3 Application Field and Working Principle

MXP4KE180AE3 is a TVS diode (Transient Voltage Suppression Diode) device mainly used in automotive applications. It is designed to help protect important electronic equipment from transient voltage and over voltage surges. It is constructed of a hermetic, surface mount package with a built-in electrostatic Discharge (ESD) protection. It also contains a ESD circuit rating of 15kV HBM (Human Body Model).

The MXP4KE180AE3 provides low capacitance protection from over voltage transients and electrical overstress (EOS) due to its bipolar transistors. The device offers an ESD clamping performance according to the IEC61000-4-2 Std. This device can also be used in a multitude of applications such as power supply, power over Ethernet (PoE), data lines, personal computer protection, automotive and telecommunications.

The working principle for the MXP4KE180AE3 is relatively simple. Essentially, when an over voltage or transient occurs, the TVS diode acts as a voltage clamp to protect the surrounding components from damage. The diode has a rated breakdown voltage, such as the MXP4KE180AE3 has a 180V breakdown voltage, meaning whenever the voltage exceeds 180V the diode will turn on to protect the surrounding components. Once the voltage drops back below the breakdown voltage, the diode turns off and resumes normal operation.

The MXP4KE180AE3 is extremely reliable and has a wide operating temperature range, making it ideal for many automotive and industrial applications. It is constructed with a hermetic, surface mount package which makes it easy to install and offers superior performance. The device also features a low capacitance of <3.0pF across all TVS diodes, making it ideal for power over Ethernet (PoE) applications.

The MXP4KE180AE3 is a flexible and robust TVS diode designed to protect against over voltage and transient events. It can be used in a wide variety of applications such as automotive, telecommunications, power supplies, power over ethernet (PoE),and data lines. It offers a low capacitance of <3.0pF as well as an ESD rating of 15kV HBM. The device is extremely reliable and superior performance, making it an ideal choice for many automotive and industrial applications.
