Introduction

Transient Voltage Suppressors (TVS) are the main form of protection for sensitive electronic components from over voltage transients induced by electrostatic discharges (ESD), lightning, inductive switching and other sources. The MXSMCJ58CA is one of the Transient Voltage Suppressors available in the market that provides superior ESD and Inductive Switching protection. In this article, we will discuss the application field and working principle of MXSMCJ58CA.

Application Field

Due to its low capacitance, the MXSMCJ58CA is widely used in high frequency applications such as communication systems, 8051microcontroller, USB ports, LCDs, MCUs, microprocessors, automotive systems, distributed systems, graphic controllers, and more. It provides EMI protection as well, reducing the impact of externally induced electrical noise on adjacent components.

Working Principle

The MXSMCJ58CA works by providing a high breakdown voltage for the application it is being used. It works by clamping on to the voltage during an over voltage event, such as an ESD surge, and sending the surge current to ground. Then, the breakdown voltage of the MXSMCJ58CA is exceeded and the surge current is clamped to reduce the surge’s voltage to a limited level.The MXSMCJ58CA is a unidirectional device, meaning that it is designed to protect against surges that enter into the protected device from the positive supply rail. The voltage has to exceed the breakdown voltage of the device in order for it to perform its job correctly.

Features

The MXSMCJ58CA is designed with some features that help make it an easier and safer option for high frequency applications. Some of these features include:• High AC Transient Immunity (up to 8kV)• Low capacitance (down to 5pF)• Low Static Leakage Current (down to 0.5nA)• Low Breakdown Voltage (down to 5V)• Fast Rise Time (down to 10ns)• High Voltage (up to 10V)

Conclusion

The MXSMCJ58CA is one of the best transient voltage suppressors (TVS) available in the market today. It is designed to provide superior ESD and Inductive Switching protection, and to do so quickly and safely. It also features a low capacitance and high current capabilities, making it suitable for a wide variety of high frequency applications.
