MXL5KP11CA Circuit Protection

TVS – Diodes

TVS (Transient Voltage Suppressor) diode is a high-performance form of semiconductor which was designed for the purpose of protecting electronic components from external transients. It is often used to protect against spikes in electrical current and voltage during system operation or in situations where there are potential electric shock hazards. Additionally, these diodes are used for their ability to limit signal propagation and reduce power losses. The MXL5KP11CA is a type of TVS diode, and its application fields and working principle will be detailed herein.

Application fields

The MXL5KP11CA diode is designed for protecting high-speed logic devices from electrostatic discharge (ESD) damage, as well as for providing overvoltage protection for a variety of industrial, automotive, and consumer electronics circuits. The high ESD and transient protection afforded by these diodes make them ideal for use in communications, industrial, medical, and consumer electronic devices where ESD and surge protection are essential. Furthermore, the MXL5KP11CA can also provide line-ups to selectively enable/disable selections within systems or to provide internal bus leveling or isolation.

Working principle

The MXL5KP11CA works on the principle of a zener-diode junction that reactions to voltage or current surges. As overload of electrical current or voltage occurs, the diode switches to a low-dynamic-resistance state, clamps the voltage or current, and dissipates the transient energy. The diode also provides short circuit protection by limiting the current in the event of a short circuit. The protection can also be augmented with the addition of various forms of EMI filters, load resistance, snubber networks, and other components.

The MXL5KP11CA diode also features an ultra-low capacitance junction that helps ensure that high-speed digital systems operating at frequencies up to 1GHz are protected. Additionally, since this type of diode has a low on capacitance, it has minimal impact on high speed, low voltage circuits even during high voltage transients.

Conclusion

The MXL5KP11CA is a low-capacitance TVS diode designed for high-speed, low-voltage applications. It provides transient and ESD protection for a wide range of electronic components, and can also limit signal propagation and reduce power losses. The diode’s ultra-low capacitance junction ensures that high-speed digital systems operating up to 1GHz are adequately protected, and its low-on capacitance makes it suitable for use in a variety of high voltage transient conditions.
