Introduction

MXL15KP64A is a Transient Voltage Suppressor (TVS) diode from Motorola. Designed as an automotive-grade component, the device is available in an SC-39A package. This diode features 1500W peak power and is well-suited for various applications in automotive, automotive lighting, industrial, and military applications.

Features

The MXL15KP64A is a 5.6V bidirectional transient voltage suppressor diode. It is designed for improved ESD protection and overvoltage protection in applications exposed to electrostatic discharge. The device has a reverse stand-off voltage of 5.6V, reverse breakdown voltage of 7.5V, and forward conduction voltage of 5.5V. With its high peak power rating and low capacitance, it can suppress high-energy spikes up to 1500W. The device is AEC-Q101 qualified and is suitable for automotive applications.

Application Fields

The high peak power rating of the MXL15KP64A makes it suitable for various applications. It can be used for ESD protection in automotive, automotive lighting, military, and industrial applications. It can also be used for EMI suppression and TVS protection. The device is well-suited for high-power systems exposed to transients and overvoltages.

Working Principle

TVS diodes like the MXL15KP64A are designed to protect sensitive circuitry from transient phenomenon and overvoltage. The device works by clamping the voltage at a predetermined level determined by the breakdown voltage. The peak power rating of the device determines the amount of power it can absorb during a transient. When exposed to an overvoltage, the diode starts conducting in reverse bias direction, instantly clamping the voltage to the breakdown voltage. The voltage is clamped and the device dissipates the surge and absorbs the energy. The diode then returns to reverse breakdown voltage, ready for another application cycle. The capacitance of the device is also an important factor. The capacitance determines the degree of absorption and the speed at which the device clamps the voltage. Low capacitance diodes are better suited for high-power systems as they provide more instant protection.

Conclusion

MXL15KP64A is a high-power Transient Voltage Suppressor (TVS) diode from Motorola. With its 1500W peak power rating and SC-39A package, the device is suitable for automotive, automotive lighting, military, and industrial applications. It can be used for EMI suppression, ESD protection, and transients protection. The device clamps the voltage at a predetermined breakdown voltage and dissipates the surge. The capacitance of the device determines the degree of absorption and the speed at which it clamps the voltage.
