MP4KE220AE3

Transient Voltage Suppressors (TVS) are a type of electronics components used to protect against transient over-voltage events in an circuit. Also commonly referred to as Surge Suppressors, they are commonly found in all types of equipment to protect against sudden voltage changes as well as sudden voltage rise events. The MP4KE220AE3 is a type of TVS from ON Semiconductor and is used to protect against transient over-voltages in many applications such as industrial and automotive.

Applications

This device is designed to safeguard sensitive electronic components against voltage transients induced by lightning, electrostatic discharge (ESD), inductive switching, and other causes of transient over-voltage. It is also certified to meet UL 94V-0, UL 1449 4th Edition and IEC 61000 standards, making it an ideal choice for applications requiring these standards. Additionally, the MP4KE220AE3 is OPTI-MOS P-Channel TVS with a low capacitance design. This makes it ideal for protecting sensitive electronics from high voltage transients while maintaining a low capacitance performance over a wide range of frequencies. Lastly, this device is also integrated with a reverse-biased line protection feature which enables it to provide effective protection from both 5V and 12V transient over-voltages.

Working Principle

The working principle of the MP4KE220AE3 is based on the principle of avalanche breakdown. This breakdown occurs when a large number of electrons are caused to flow in a semiconductor device, usually by the application of a high electric field. This causes the electrons to move in a large number from an area of high electric field to an area of low electric field, resulting in the avalanching of electrons. The result is a large current flowing in the device that is able to suppress transient over-voltage in the circuit. The MP4KE220AE3 is specifically designed to protect against surge voltages induced by induced transients. It does this with its low capacitance design and integrated reverse-biased line protection feature. In addition, this device has an input clamp that clamps the input voltage to the device’s breakdown voltage, also known as the “avalanche voltage.” This ensures that the device is not damaged by excessive surges. Overall, the MP4KE220AE3 is a great choice for applications needing reliable over-voltage protection. The device is constructed with a high-performance, low-capacitance design, and is certified to UL 94V-0 and UL 1449 4th Edition standards. This makes it reliable and capable of protecting against extreme surge voltages.
