MXP6KE20CA is a component in the television station diode family which provides a convenient protection against the effects of excessive current. It is always used as a single device or in pairs. Usually, to protect the system from transient overvoltage, it is used together with a transient suppressor.

A TVS diode, also known as a Transient Voltage Suppressor, is a two-terminal device typically used to suppress voltage transients in electrical systems. It is a specialized form of a Zener diode designed to absorb and dissipate large amounts of energy. TVS diodes provide protection against lightning strikes and other transient overvoltage events.

The MXP6KE20CA is a silicon-based diode designed to clamp and protect circuits from transient overvoltages. It has a Vbr of 20 volts and an Ipp of 200mA. The MXP6KE20CA also offers superior noise protection against voltage surges. It is able to absorb hundreds of volts spikes with a peak pulse current in the range of 100mA.

The MXP6KE20CA consists of a metal oxide varistor (MOV) and a Zener diode. When the diode is subjected to a voltage transient greater than the rated breakdown voltage, the diode turns on and the MOV absorbs the energy of the transient. The MOV is designed to conduct current above its rated breakdown voltage, forming a “clamping” action to protect the circuit from overvoltage. The Zener diode, meanwhile, provides a "soft" limit to the voltage transient, allowing the diode to absorb most of the energy and dissipate it rather than passing it on to the device it is intended to protect.

MXP6KE20CA is a space-saving and efficient diode which is mostly used in radio frequency (RF) protection applications. It can also be used for protection in systems such as LED configuration protection and automotive design. The diode can be used in combination with other components such as polymeric positive temperature coefficient devices, ac fuses, or zeners for added protection to system circuitry.

In a typical protection scheme, the MXP6KE20CA is connected between the power supply of an electronic device and its ground. When the voltage rises beyond the TVS diode’s maximum rated voltage, the diode activates and absorbs the transient voltage, protecting the circuit. The MXP6KE20CA is capable of handling large pulse currents without destroying itself and can safely absorb up tens of volts and hundreds of watts of energy.

The MXP6KE20CA is an excellent choice for providing effective protection against power transfer transients, high-speed switching applications, and static electricity. It can also provide a reliable and cost-effective alternative to protecting electronic components in automotive, communications, and other industrial applications. Its consistent performance and long lifetime make it suitable for many different applications.
