MXL1.5KE6.8A Circuit Protection

MXL1.5KE6.8A Application Field and Working Principle

MXL1.5KE6.8A Device is a TVS diode designed to protect sensitive electrical equipment’s from damage due to voltage transients. TVS diodes also known as Transient Voltage Suppressors, Transient Voltage Spikes Protector (TVSP), or Transient Voltage Surge Suppressors (TVSS). They are widely used in application that requires the protection of circuits from over voltage transients caused by lightning, inductive switching, electrostatic discharge, and load dump.

The MXL1.5KE6.8A is unidirectional element which features powerful suppression of transients to 14.0 kilovolts peak pulse power. It is designed for use in applications where low breakdown voltages is required, therefore, its most useful in locations that may be exposed to high levels of electrostatic discharge (ESD). The working principle of the TVS diode can be understand best using a diode circuit diagram, as follows.

The graph shown in the above figure illustrates the phenomenon of “clamping” of a transient waveform. In a simple diode circuit, the diode will conduct during the negative half cycle of the transient while it will be in high resistance state during the positive half cycle. This results in clamping of the positive half of the peak of the waveform to the diode’s forward voltage drop. This phenomenon of the diode is used in TVS diodes to protect sensitive equipment’s from high voltage spikes and surges.

The MXL1.5KE6.8A device is designed to limit the surge current generated due to voltage transients which the transient waveform may cause. It operates on a principle of reverse bias and transient over-voltage protection by limiting the peak pulse power and clamping voltage to a low and safe level for sensitive components. Upon reaching the rated voltage that exceeds the protection level, the device will quickly clamp the excess voltage, limiting it to the clamping voltage of the device. This protects the circuit from further damage. The reverse leakage current of the device is low and is primarily used to protect equipment’s from large, destructive voltage transients.

The MXL1.5KE6.8A is a great example of a TVS diode, capable of providing reverse bias and over-voltage protection. These devices are used in a wide range of applications that require maximum surge current and clamping protection. They are suited for a wide range of consumer electronics and industrial applications, such as automotive, telecommunications, networking, and power supplies. The device also provides excellent electrical performance, highly reliable failure protection, and low cost. It is the perfect choice for applications that require over-voltage and/or over-current protection.

In conclusion, MXL1.5KE6.8A is a TVS diode that is designed to protect sensitive electronic device used in a wide range of applications. It is capable of providing reverse bias and over-voltage protection, along with excellent electrical performance, highly reliable failure protection, and low cost. It is the perfect choice for applications that require over-voltage and/or over-current protection.
