Transient Voltage Suppressors (TVS) are widely used in various applications. They are used to limit voltage and current which could otherwise damage a circuit or cause it to malfunction. TVS diodes are especially beneficial to protect circuit components from transient voltage events and from induced high voltage noise in circuits. The MXP5KE75CA is a member of this family of TVS diodes. This article provides an overview of the MXP5KE75CA application field and its working principles.

MXP5KE75CA Application Field

The MXP5KE75CA is designed for transient voltage protection and ESD protection. This device is designed to protect from transients in the range of ±5kV HBM, ±3kV CDM events, and 1.5kV IEC 61000-4-2 contact discharges. It also provides low clamping voltage and quick response time. This versatile device is suitable for working with a wide range of applications that require high-speed operation, such as for I/O ports, communications, automotive, industrial, consumer, electronics and more.

MXP5KE75CA Working Principle

The MXP5KE75CA consists of a diode section and a resistor section. During the event of a sudden voltage increase, the diode section starts to conduct and thus diverts the excess current, limiting the voltage and protecting the device from damage. The resistor section gradually absorbs the current surge to dissipate the energy and provide a current limit. The device also has an operating terminal which is used to set the threshold voltage at which the diode will become conductive and start limiting the voltage.

The device can be operated in unipolar mode, with just a single cathode to protect against positive surge, or in bipolar mode by connecting both anode and cathode to the circuit. In unipolar mode, the device has very low capacitance and leakage current, while in bipolar mode the device provides high peak current ratings and fast response times. The device works for both the adjustable and fixed voltage threshold applications.

Conclusion

The MXP5KE75CA is an ideal device for transient voltage protection. It provides protection from sudden voltage increases, has fast response time, low clamping voltage, and can operate in either unipolar or bipolar mode. This device is suitable for a wide range of applications, including I/O ports, communications, automotive, industrial, consumer, electronics and more.
