MAP4KE120AE3

TVS - Diodes

The MAP4KE120AE3 is a TVS – diodes device designed to protect electronic equipment from input transients generated by lightning and other sources. It is used to protect sensitive electronic components from damage caused by electrostatic discharge (ESD) and electrical overstress (EOS). TVS diode technology provides superior protection from transient voltage events by clamping voltage and current surges that would otherwise cause significant harm to circuit components.

The MAP4KE120AE3 is designed to protect high-speed data lines that need to be protected from a variety of sources such as lightning and electrostatic discharge. The device provides superior low capacitance, low clamping voltage, wide dynamic range and fast response to transient events. The MAP4KE120AE3 is available in a variety of packages, including SMA, QFN, and DIP, for a variety of applications.

Application Field

The MAP4KE120AE3 is used in a variety of applications that require ESD and EOS protection. It is most commonly used to protect sensitive electronic components in consumer electronics and computer equipment, such as cell phones, laptop computers, and printers. It also has applications in automotive systems for on-board diagnostics, memory protection, and motor control and in industrial systems such as control circuits, instrumentation, and medical devices.

Working Principle

The MAP4KE120AE3 works by monitoring the voltage at the input terminals and detecting any transient voltages. When a transient voltage spike occurs, the MAP4KE120AE3 will clamp the voltage down to a safe level. This clamping effect is achieved through the construction of the TVS device which contains a small capacitance along with a charge storage element. As the voltage spike occurs, the charge storage element will fire and release electrons to drive the voltage spike back to ground, thus limiting the voltage spike to a safe level.

The MAP4KE120AE3 is designed to work with both AC and DC power sources. It has a high surge capability up to 1000 volts, which makes it suitable for protecting components from both ESD and EOS events. The device is capable of clamping voltages up to 175 volts, which makes it suitable for protecting against transient events generated by lightning and ESD.

The MAP4KE120AE3 also provides excellent temperature stability and wide dynamic range, which make it suitable for a wide variety of applications. It is also RoHS and REACH compliant.
