A TVS-diode is a type of semiconductor device that can prevent electrical transients from damaging a circuit. The MX1.5KE11AE3 is a particular type of transient voltage suppressor (TVS) diode with some specific characteristics. It is designed to protect sensitive electronic components from exposure to transient overvoltage.

From a physical standpoint, the MX1.5KE11AE3 is a single diode with two opposing ends. One end is held at a positive voltage and the other at a negative voltage, while the middle of the diode forms a PN junction. When a transient voltage greater than the diode\'s breakdown voltage is injected into the diode, it causes a short circuit, which then dissipates the transient energy into the surrounding environment.

The breakdown voltage is typically measured in volts, and is divided into three parts—the clamping voltage, the peak allowable current, and the peak energy value. The MX1.5KE11AE3 has a breakdown voltage of 1.5kV, peak current of 110A, and peak energy of 3.2J. The peak current is the maximum current the diode is able to dissipate before it is destroyed, while the peak energy is the total energy a diode is able to absorb before it is destroyed.

The MX1.5KE11AE3 is widely used in a variety of applications. It is important for protecting sensitive electronic components from transient overvoltage in consumer electronics, cell phones, industrial automation, medical systems, automotive electronics, and more. It is also useful for controlling electromagnetic interference, reducing conducted emission, and suppressing higher frequency disturbances.

The MX1.5KE11AE3 works by instantaneously limiting the voltage at its anode to its breakdown voltage, which is approximately equal to its clamping voltage. This eliminates any further increase in voltage and protects the circuit from being damaged by transient voltages. The diode also reduces the amount of time the transient is in contact with sensitive components, protecting against any potential damage.

Additionally, the diode will dissipate the transient energy in the form of heat, instead of the circuit carrying the energy. This will help protect components and systems from thermal damage, due to the increased flow of current during transients.

In conclusion, the MX1.5KE11AE3 is a particular type of transient voltage suppressor (TVS) diode that is designed to protect sensitive electronic components from exposure to transient overvoltage. It features a breakdown voltage of 1.5kV, peak current of 110A, and peak energy of 3.2J. The diode is widely used in a variety of applications, including consumer electronics, industrial automation, medical systems, automotive electronics, and more. It works by instantaneously limiting the voltage at its anode to its breakdown voltage, reducing the amount of time the transient is in contact with sensitive components, and dissipating the transient energy in the form of heat.
