Introduction to TVS-Diodes

Transient Voltage Suppressors (TVS-Diodes) are specialized diodes, typically made from Silicon Carbide (SiC), which are designed to protect electronic circuits from ESD (Electro-Static Discharges), EFT (Electrical Fast Transients), and even lightning strikes. A typical application for a TVS-Diodes is protecting a computer’s memory from ESD and EFT events, which can cause data-corruption, system crashes, and even permanent damage to the hardware.

MXP5KE11A Application Field and Working Principle

The MXP5KE11A series of TVS-Diodes is designed to protect electrical and electronic systems from ESD and EFT events which occur at voltages up to 11V. The MXP5KE11A series has an application field which ranges from electronics, computers and consumer electronics to industrial and marine environments.The MXP5KE11A works by absorbing the energy of a transient event and dissipating the energy into resistive element(s). It is designed to provide a fast response to an ESD or EFT event, with a turn-on voltage of 6.5V that is able to react within a few nanoseconds (or less). Upon encountering a surge event, the MXP5KE11A acts like a clamping circuit, absorbing the transient energy and dissipating it to the specified resistor to prevent damage to other components or circuits.The MXP5KE11A features several design advantages that can make it a superior choice for many applications: its low capacitance of 0.5pF makes usage in high-speed data circuits possible, protecting high-speed Ethernet lines from ESD or EFT events, and its high-dv/dt capability (aka surge capability) allows it to handle even the strongest surges, without sacrificing its performance.

Conclusion

The MXP5KE11A is a specialized TVS-Diode for providing elevated protection from ESD and EFT events with voltages up to 11V. It features design advantages such as low capacitance and high-dv/dt capabilities enabling it to be used in various applications, including low-speed digital circuits and high-speed Ethernet connections. Its fast response time and ability to dissipate even the strongest surges make it an excellent choice for applications which require more robust protection.
