MPLAD6.5KP75A Application Field and Working Principle

Transient voltage suppressors (TVS) are devices that act as a voltage protection by providing a short path to ground during transient events. The MPLAD6.5KP75A is one such device, a 6.5V bidirectional ESD TVS diode that is specifically designed to protect USB port interfaces from ESD and other high voltage transients.

Application Field

The MPLAD6.5KP75A has a wide range of applications in the electronic industry, with its large breakdown voltage of 6.5V making it suitable for use in applications requiring protection from higher voltage transients. Commonly used in USB port interfaces, the MPLAD6.5KP75A can also be applied to other parallel, series or multi-level protection schemes, or as part of a combination circuit.

Working Principle

The MPLAD6.5KP75A works on the principle of reverse polarity protection. When the input voltage exceeds the breakdown voltage, the device becomes conductive and provides a low impedance path to ground. This ‘shunts’ the excess voltage away and limits the maximum voltage that can appear across the protected circuit. The reverse polarity functionality also prevents the device from conducting any current under normal operation. By making sure that the input current is limited within the safe operating limits of the device, it ensures that the protected circuits are not damaged by excessive current flow.The TVS diode also includes a unique EMI/RFI filter which is designed to protect the device from transient events as well as interference from external sources. This filter is composed of a number of small capacitors and resistors in series, effectively reducing the magnitude of disturbances before they reach the protected circuit.

Conclusion

The MPLAD6.5KP75A is an efficient and reliable 6.5V bidirectional ESD TVS diode, specifically designed for use in USB port interfaces. The diode works on the principle of reverse polarity protection, providing a low impedance path to ground when the input voltage exceeds the breakdown voltage. The device also includes a unique EMI/RFI filter which effectively reduces any disturbances before they reach the protected circuit. All of these features combine to make the MPLAD6.5KP75A an effective and reliable protection device, suitable for use in a diverse range of applications.
