Transient Voltage Suppressors (TVS) are devices used to protect integrated circuits and other electrical components from damaging transients, such as lightning, voltage spikes, electrical surges and switch mode power supplies. The MXSMLJ24CA is an unidirectional TVS diode that can be used across a variety of applications and is able to protect lines from voltage transients up to 24kV. This article will discuss the application field of this part and its working principle.

MXSMLJ24CA Application Field

The MXSMLJ24CA TVS Diode is designed for space critical applications such as laptops, tablets, and other portable devices. It provides protection from voltage transients on electrical lines and interfaces up to 24kV. Its miniature size allows for easy integration into board space-constrained designs. The device is suitable for use in ESD and electrical surge protection in the automotive field, consumer electronics, industrial, medical, and communication applications. Due to its low capacitance, this part can be used in telecom and high speed data line applications.

Working Principle

The MXSMLJ24CA is an unidirectional device and connects the power line ground and system ground for protection against voltage transients. When a voltage transient occurs, the diode becomes forward biased, which has the effect of clamping. During this process, the diode diverts the excess energy to ground, thus protecting the connected system. This diode also serves as a protection during electrostatic discharge (ESD). The diode can divert the excess energy to ground, preventing damage to the system. The diode is also able to suppress repetitive pulses, which helps to protect against over voltage conditions. Finally, the MXSMLJ24CA is designed to remain in its forward biased state until the transient voltage falls below the hold-off voltage and the diode can return to its reverse bias state.

Conclusion

The MXSMLJ24CA TVS diode is a space-saving, low capacitance device that provides reliable overvoltage protection up to 24kV. This diode can be used in a variety of applications, such as automotive, consumer electronics, industrial, medical, and communication. Its unidirectional behaviour makes it suitable for ESD and electrical surge protection. During a voltage transient, the diode becomes forward biased, which allows it to divert excess energy to ground. Finally, the diode is designed to reset itself once the voltage transient has subsided.
