MXP4KE220AE3 is an unidirectional Silicon Avalanche Diode (SiAVD) that belongs to the Transient Voltage Suppression (TVS) Diode family. The device is used to protect against electrical transients, generated mainly in the automotive or industrial environment, which can arise from events such as lightning, induced fast transients, load dump and ESD.

MXP4KE220AE3 has a maximum Ipp peak pulse current of 2.2kA and enables current to be shunt from a wide range of device sizes. It can be commonly used in switching power supplies, communication systems, portable devices, automotive and consumer electronics. The MXP4KE220AE3 offers high speed, low internal capacitance and fast recovery time.

MXP4KE220AE3 is a bidirectional TVS Diode, designed for symmetrical transient protection of AC power line surge in high-speed communication system. It also fits into different standard packages, with easy installation and integration. The device has an ultra-fast peak pulse current of 2.2kA for pulse width less than 1μseconds.

The working principle of MXP4KE220AE3 is based on its SiAVD diodes, which are specifically designed to provide reliable protection against transients for wide voltage range applications. During a transient, when the voltage of the device exceeds the breakdown voltage, an avalanche breakdown occurs with a small current, allowing the transient current to be dumped safely. This produces a reverse voltage spike that can be reflected back to the signal path, and eventually dissipates in the clamping components.

MXP4KE220AE3 has a variety of application fields, including overvoltage protection, power electronics protection, automotive and industrial applications, data line protection and communication system protection. It is suitable for all kinds of power supply lines, solenoids, motor drive circuits and power circuits. The device is also compatible with a wide variety of smart power controllers, circuit protection modules, and flexible circuit assemblies.

In conclusion, MXP4KE220AE3 is a high-performance TVS Diode designed to provide robust and efficient protection against transients. Its applications ranges from overvoltage protection to automotive and communication systems. The device also has a fast peak current of 2.2kA, and a wide variety of packages to choose from. It offers excellent overvoltage protection and high surge capability.
