Surge protection is an essential component in many power systems and it has the potential of greatly reducing the amount of damage which may be caused by power surges as well as increasing the safety and reliability of the system. The MAP4KE47AE3 is a unidirectional Transient Voltage Suppression (TVS) diode which is designed specifically for this purpose. It has been designed to protect against both overvoltage transients and Electrostatic Discharge (ESD) in the range of 5V to 100V.

Working Principle: The MAP4KE47AE3 diode works by suppressing the voltage surge that may occur in a power system. It consists of a zener diode and a reverse biased avalanche diode connected in parallel. The zener diode works by providing a low impedance path for current which discharges the capacitor associated with the offending voltage. The avalanche diode works by providing a fast switching capability which can quickly shut down the circuit. Both components of the MAP4KE47AE3 work together to effectively protect the system from voltage overshoots, reverse EMF transients, and ESD events.

Application fields：The MAP4KE47AE3 can be used in a wide range of applications, from computer motherboards and hard drives, to automotive and telecommunications systems. It is also an ideal choice for those who want to upgrade existing systems to provide improved surge protection. Some of the most common applications where the MAP4KE47AE3 can be employed are computer motherboards, automotive lighting systems, CCTV systems, and home theater systems.

The MAP4KE47AE3 diode provides a great level of protection against various types of surges and ESD events. It is a small, compact device with a wide range of applications, making it an ideal choice for those looking to protect expensive electronic equipment from surges and voltage overshoot issues. Thanks to its high surge capability, fast response time, and low dynamic capacitance, the MAP4KE47AE3 is an excellent choice for many power protection projects.
