MXLCE170A Series devices provide very low off-state leakage current of less than 1nA at an operating voltage up to 6.1V. Featuring robust SMAJ and SMBJ packaging, these devices provide stable and reliable operation in harsh environmental conditions. They are well-suited for portable and automotive applications due to their low power consumption and they have high excellent surge capability of up to 1700W peak pulse power per line. This parts is ideal for the protection of DC power lines, audio/video ports, and embedded systems.

MXLCE170A Working Principle

The MXLCE170A series are diffused junction devices designed for the protection of data and transmission lines from high voltage transients and other ESD events. The device integrates clean and reliable ESD protection and a low on-state capacitance of less than 10pF. It is triggered into conduction by an electrostatic discharge measuring from 2KV to 6KV.

The device forms an electrically insulated oxide layer on the gate of a MOSFET and acts as a protected switch which shuts off, or shields the device from further ESD shocks. The majority of the transient voltage is then shunted to ground thus safeguarding the components in the system. The MXLCE170A operates at a clamping voltage of typically 7.3V.

MXLCE170A Application Field

MXLCE170A devices can be used in many applications in order to protect systems or components from ESD damage. Their excellent ESD tolerance and low leakage current enable them to be used in consumer electronics, automotive, and industrial applications.

MXLCE170A devices are commonly used in audio and video interfaces. The devices guard against electrostatic discharge, which can damage low-voltage circuits and cause data interruptions. They can also be used in PC motherboards and cameras to protect against damage from ESD strikes in automotive electronics.

The devices are also used in data storage and transmission systems such as USB, SATA, and Ethernet. The low capacitance of the MXLCE170A devices make them an ideal choice for these applications since they minimize distortion due to interference with high frequency data.

These devices also offer protection from ESD transients for portable devices. Laptops and tablets are particularly vulnerable to voltage transients and ESD induced damage, and the MXLCE170A series offers excellent protection against these types of events.

MXLCE170A devices can also be used in Industrial Automation and robots. The devices provide high-level protection for these applications and offer robust performance in temperature extremes and other harsh conditions.

Conclusion

The MXLCE170A series from Vishay Semiconductor offer best-in class ESD protection for a wide range of applications. Their low on-state capacitance and excellent protection against ESD make them an excellent choice for protecting sensitive components and systems from voltage transients.
