MP6KE170AE3

TVS-diodes have been used for the protection of mother boards, electrical systems, and data lines. The MP6KE170AE3 is a TVS-diode designed primarily for criminal prevention in automobiles. This protection package provides a threshold voltage of 17V, a breakdown voltage of 30V, ESD protection of up to 3500W, and a maximum peak pulse current up to 150A. This diode is particularly suitable for auto ECU (Engine Computer Unit) protection and ESD (Electrostatic Discharge) protection.

Application Field

The MP6KE170AE3 is applicable for reverse polarity protection, polarity reversal protection, and over-current protection. It can be used in automobile ECU protection, such as Electronic Control Units (ECUs), Electronic Throttle Control (ETC) systems, and Airbag Control Units (ACUs). It is also suitable for fuel pump protection, uninterruptible power supply, and other necessary electronic circuits applications. The MP6KE170AE3 can provide protection against high voltage transients and surges caused by electromechanical switching.

Working Principle

The MP6KE170AE3 uses a Zener diode as its core. When a TVS-diode is necessary, the Zener diode will clamp and redirect the surge current away from the device. During an overvoltage, the Zener diode will be caused to break down, allowing a surge current to be conducted away from the device. This will limit the voltage surge experienced, and protect the protected device from damage. The MP6KE170AE3 features a dual mode surge response so it can react accurately to different types of surges.

The MP6KE170AE3 also has an electrostatic discharge (ESD) protection, which is enabled by an on-chip bi-directional ESD protection circuit. This circuit provides fast and extremely effective high-speed clamping of lightning-led, electrostatic discharge, and transient voltage signals. The device is also designed to minimize power dissipation and EMI (electromagnetic interference) to eliminate potential interference with other components.

Conclusion

The MP6KE170AE3 is a powerful TVS-diode, providing efficient and reliable protection against high voltage transients, ESD, and electrostatic discharge. It is suitable for automobile ECU protection and fuel pump protection. It offers a breakdown voltage of 30V, a maximum peak pulse current up to 200A, and ESD protection of up to 3500W. Its dual mode response and low capacitance make it ideal for a variety of applications.
