TVS – Diodes (Transient Voltage Suppressors) are used mainly in applications where severe ESD and transient voltage spikes can cause intermittent or permanent failure. The application of TVS diodes is most commonly seen in communication and control systems. The MX5KP10A is a Transient Voltage Suppressor (TVS) diode specifically designed for protecting Electro Magnetic Compatibility (EMC) from electrical transients and fast transient bursts.

The device is designed using a combination of surge current handling capability, clamping voltage, and low temperature coefficient. Its optimized shallow junction design and internal safety emphasis make it ideal for EMC protection applications. It has a voltage clamping of 16V@5A and a DC breakdown voltage of 10V. The unique Zener structure of the MX5KP10A features zero-energy clamping, fast response time, and low clamping voltage, making it ideal for transient voltage protection applications.

The working principle of the MX5KP10A is to reduce the effect of environmental transients on electronic systems. Transient voltage spikes(TVS)are electro-magnetic pulses or EMI waves that occur naturally in the environment due to lightning strikes, switching operations, and other related phenomena. Transients can be damaging to electronic systems, and in extreme cases can cause permanent damage or malfunction. The MX5KP10A is designed to act as a ‘safety valve‘, absorbing incoming voltage transients and dissipating them safely, thus protecting sensitive electronic components.

The MX5KP10A is a popular choice for high-frequency communication and control systems, where it is often used in conjunction with low-capacitance ESD protection devices. It can protect signal lines, including cellular, optical, Bluetooth, trunk, and coaxial cables, in addition to printed circuit boards (PCBs).

To control the flow of the current, the device works by quickly shunt-clamping, which is the process of diverting higher currents away from vulnerable components to ground. This is done by using an operating voltage (Vz) slightly lower than the voltage of the EMI wave. As soon as the surge voltage rises above the “zener” voltage, current is shunted away from the sensitive components, safely dissipating the energy through the MX5KP10A’s internal resistance. When the environmental transient has passed, the device returns to its previous state, ready to protect against the next incident.

TheMX5KP10A also features integrated overvoltage protection, which helps to prevent system shut down caused by electrostatic discharge (ESD) and other high voltage spikes. Its integrated loop out and latch protection mechanisms provide additional safeguards against overvoltage incidents.

As a widely used TVS diode, the MX5KP10A is the ideal choice for EMC protection applications. Its optimized shallow junction design, with integrated overvoltage protection and latch mechanisms, provide the peace of mind that systems and components are protected against voltage transients and EMI related surges. It offers protection against overvoltage conditions, making it perfect for ensuring your communications systems are safe from dangerous surges.
