MPLAD15KP170AE3 Application Field and Working Principle

Introduction

The MPLAD15KP170AE3 is a low capacitance bidirectional transient voltage suppressor (TVS) diode specifically designed to protect data line from electro-static discharges (ESD) and other transient voltage events. The diode’s low clamping voltage and low capacitance make it ideal for data transmission lines. This TVS diode features a low dynamic resistance and a high surge current rating providing superior ESD protection.

Application Field

The MPLAD15KP170AE3 is designed for use in electronic systems and systems requiring an overvoltage protection such as automotive and communication applications, consumer electronics, and industrial control systems. The TVS diode is designed to protect against overvoltage conditions, such as those generated by ESDs, electrical fast transients (EFTs), and lightning. It is also suitable for use in data transmission lines that require a low capacitance device to maintain signal fidelity.

Working Principle

When exposed to an overvoltage event, the MPLAD15KP170AE3 will act as a short circuit and limit the voltage across its terminals to a safe level. The device will quickly clamp the transient voltage to the desired breakdown voltage. This TVS diode features a low dynamic resistance and a high surge current capability, enabling it to absorb high transient energy and provide ESD protection. The device also features overvoltage protection by limiting the voltage across its terminals to the breakdown voltage (VBR) which can range from 5.8 V to 170 V. When the device is operated above the breakdown voltage, it will limit the current and clamp the voltage at the breakdown voltage. The device is also designed with a claimed capacitance of 0.2 pF between the anode and cathode, which minimizes signal degradation and maintains the signal integrity of data transmission lines.

Conclusion

The MPLAD15KP170AE3 is a low capacitance bidirectional transient voltage suppressor (TVS) diode designed to provide superior ESD protection and overvoltage protection. The device features a low dynamic resistance and a high surge current rating, enabling it to absorb high transient energy. The diode’s low clamping voltage and low capacitance makes it ideal for data transmission lines, while its claimed capacitance of 0.2 pF minimizes signal degradation and maintains signal integrity. The device is suitable for use in automotive and communication applications, consumer electronics, industrial control systems, and other electronic systems that require an overvoltage protection.
