Introduction

TVS (Transient Voltage Suppression) diodes are widely used to protect electronics against overvoltage transients of ESD (electrostatic discharge) events and lightning induced surges. The MXLSMBG40CAE3 is a unidirectional TVS diode from the SMA package designed specifically for use in EMC and automotive applications.

Application Field and Working Principle

The MXLSMBG40CAE3 is designed for ESD and surge protection in applications such as automotive, consumer electronics, computers, and industrial control systems. It is part of a line of TVS diodes that offer protection from overvoltage transients. The device is packaged in a small SMA package, which enables it to be used in a variety of applications demanding space efficiency. The MXLSMBG40CAE3 is a unidirectional TVS diode that provides protection from ESD and surges of up to 40A. The device has a stand-off voltage of 16V and reverse standoff voltage of 5V. It is capable of withstanding up to 160V reverse voltage. The device’s response time is as fast as 5ns and it offers protection up to 250V from impulse voltages. When an overvoltage transient occurs, the diode will conduct current, providing an alternate path for the surge current to flow. This reduces the voltage applied to the component it is protecting. The device is made up of two zener diodes connected back to back, which will break down inversely proportional to the voltage. As the voltage increases, the current conducted by the device increases, reducing the voltage and clamping the voltage at the reverse standoff voltage. The device also has a current limiting circuit, which helps reduce the peak surge current.The device also includes a Reverse Standoff Protection Circuit (RSPC) which is designed to protect against overvoltage transients in the reverse direction greater than the inverse stand-off voltage. The RSPC trips and will clamp the voltage at a predetermined level. This feature provides improved protection compared to regular TVS diodes.

Conclusion

The MXLSMBG40CAE3 is a TVS diode from the SMA package family designed for use in EMC and automotive applications for protection from overvoltage transient pulses. The device provides protection from ESD and surge of up to 40A with a fast response time of 5ns. The stand-off voltage is 16V and reverse stand-off voltage is 5V and it is capable of withstanding up to 160V reverse voltage. The device includes an RSPC feature which helps provide improved protection against overvoltage transients in the reverse direction.
