TVS (Transient Voltage Suppressors) diodes have been the popular go-to way of protecting sensitive electronic systems and components from overvoltage issues. The MAP4KE220CAE3 is an example of such a component. This article will discuss the application fields and working principle of this device.

Application Field

The MAP4KE220CAE3 has a wide range of potential applications including automotive, telecom and computers, measuring devices, industrial control, and consumer electronic applications such as mobile phones and gaming consoles. It\'s designed to protect CMOS devices and other sensitive electronics from overvoltage-induced damage from electrostatic discharge (ESD). The device has an on-chip autoreset feature that automatically resets the TVS diode if excessive voltage is detected. It can also absorb repeated ESD surges.

Working Principle

The MAP4KE220CAE3 is a unidirectional TVS diode with an on-chip autoreset feature. It has an integrated trigger and protection cell that is able to detect when voltage reaches a specified level found in the breakdown voltage design specification. When the breakdown voltage is exceeded, an avalanche breakdown occurs within the device, causing it to conduct current. The excess voltage is diverted from the protected circuitry, thus providing reliable protection.

The device is also able to absorb repeated ESD surges, making it suitable for use in equipment such as mobile phones. The integrated autoreset feature is also beneficial in this application as it allows the device to automatically reset itself after an overvoltage event. This prevents permanent damage to sensitive components and helps to ensure optimal performance of the installed device.

Conclusion

The MAP4KE220CAE3 is an excellent choice for protecting sensitive circuitry from ESD and overvoltage events. Its versatile range of applications, integrated autoreset feature, and ability to absorb repeated ESD surges make it an excellent choice for industrial, consumer, and automotive applications. Understanding its application fields and working principle is essential for selecting the best component for the job.
