Transient voltage suppressors, also known as TVS diodes, are extensively used in a variety of electronic circuits to protect them from high voltage spikes and current surges. The MXL1.5KE8.2AE3 is an efficient and reliable component designed for protecting electronic systems from lightning and other electrostatic discharges (ESD).

The MXL1.5KE8.2AE3 device has an axial-lead, unidirectional unidirection classification, and is designed for suppressing high-voltage spikes and conducting over-voltage transient current. It consist of a voltage regulator diode in series with a pair of back-to-back Zener diodes, mounted in an TO-252 surface-mount package. The device is offered in a hermetically-sealed, low-profile shape and is rated for an operating voltage between 10 and 55 volts with a peak power of up to 1.5 kilowatts. The maximum clamping voltage for the device is 8.2 Volts and the maximum operating frequency is 3.3 GHz.

The device is capable of protecting against ESD pulses up to 30 kilovolts (kV) in air, and up to 8 kV in contact discharge, while maintaining excellent clamping capability and low leakage current at the recommended operating voltage. The device also features excellent dV/dt ratio and minimizes ringing under certain conditions. Another important feature of the device is its high surge current handling capacity, up to 20 amperes.

The MXL1.5KE8.2AE3 has a wide array of applications, such as in protection against lightning, providing over-voltage protection to sensitive electronic components, television and satellite receivers, power supplies, and other high-definition electronic systems. It is particularly suitable for protecting high-speed communication lines such as Ethernet, USB, IEEE 1394, and HDMI.

In terms of working principle, the MXL1.5KE8.2AE3 can be described briefly as such: the device works by clamping the voltage to a certain level once it reaches a certain threshold, as dictated by its voltage regulator diode. When the device is connected to an external circuit, any excessive voltage present in the circuit causes the voltage regulator diode to become forward-biased, which allows current to flow from one end of the diode to the other, thus limiting the voltage to the device’s rated value. The Zener diodes in the device become reverse biased, and act to channel the current away from the external circuit.

In conclusion, the MXL1.5KE8.2AE3 is an effective device designed for protecting electronic systems from high voltage spikes and current surges. With the ability to suppress ESD pulses up to 30 kV in air, and up to 8 kV in contact discharge, this device provides excellent protection against lightning and other potential sources of over-voltage damage. Its wide array of applications and features make it a suitable and reliable component for a variety of electronic systems, including high-speed communication lines.
