MXL1.5KE130AE3 is a high voltage TVS diode designed to protect a variety of semiconductors, circuits, and components from electrostatic discharge (ESD), electrical overstress (EOS) and voltage transients such as lightning and induced transient voltage. This device is made up of a region of diode connected in series with a region of avalanche diode connected to their anode which can significantly improve the protection level of the circuit compared with ordinary diode.

MXL1.5KE130AE3 belongs to the class of transil diode, also known as Transient Voltage Suppressor Model (TVS diode), designed to clamp fast voltage transients and to help guard semiconductor devices from damage due to electrostatic discharge (ESD). This type of diode can carry large transient current spikes but is limited in its power dissipation with respect to normal operation. It is commonly used in fields of telecommunications, computing, medical, automotive and industrial automation. It can effectively reduce circuit overvoltage caused by ESD voltage transients for systems and components.

The working principle of MXL1.5KE130AE3 can be divided into two stages. Firstly, the peak voltage is clamped below its maximum specified maximum operating junction temperature rating. It works by providing a large on-state conduction current that diverts the excessive voltage. After then, the avalanche breakdown occurs during the off-state mode and it is responsible to protect the device from EOS. The main parameters of this MXL1.5KE130AE3 include the voltage holding range or the Rated Working Voltage, the Pulse Voltage, Maximum ESD voltage and Power Dissipation Stress. The voltage holding range describes the voltage range at which the TVS diode needs to be to clamp the excessive voltage transient. The Pulse Voltage is the rated voltage of the diode after an ESD pulse. The Maximum ESD voltage is the highest peak voltage the network. The Power Dissipation Stress is the limit of power dissipation that can be transferred to the diode. All of these parameters combined for maximum protection of a circuit from overvoltage and ESD pulses.

In summary, MXL1.5KE130AE3 is a popular Transil diode designed to protect from overvoltage and ESD pulses and suitable for a wide range of applications. It is widely used in various fields, such as telecommunications, computing, medical, automotive and industrial automation. Its features peak voltage clamping and avalanche breakdown have enabled it to widely used for robust protection of semiconductor devices and components.
