TVS (Transient Voltage Suppressor) Diodes are widely used devices for protecting electronic circuits from overvoltage transients caused by lightning, static discharge, over-voltage power events, and other electrical spikes. The MP6KE68AE3 is a unidirection transient voltage suppressor diode used for over-voltage protection of electronic components. It is suitable for a wide range of over-voltage protection applications, including automotive and telecommunications equipment.

The MP6KE68AE3 TVS diode comprises of two main components: a zener diode and a thyristor. The zener diode acts as the main over-voltage protection device, while the thyristor provides additional over-voltage protection and enables a higher peak current capacity.

When the voltage across the device exceeds the breakdown voltage of the zener diode, the zener diode starts to break down and clamps the voltage across the diode at its breakdown voltage. This clamped voltage is known as the clamping voltage. The thyristor then starts to become active, further increasing the clamping voltage of the device. This operation ensures a rapid clamping of the device’s voltage without thermal runaway.

At the same time, the thyristor protects the device from even higher voltages by providing surge current limiting. This limits the device’s current by limiting the voltage that can be applied across the device. This protects the device’s circuitry from even sudden and severe overvoltage events without having to worry about thermal runaway.

The MP6KE68AE3 TVS Diodes offer a wide range of operating voltage ratings, up to a peak pulse power of 1000W. The device also incorporates additional protection features, such as creepage distances and reinforced insulation, to meet industry standards. The device is also certified for automotive applications, which requires additional protection features such as temperature cycling, vibration tests, and moisture resistance.

The MP6KE68AE3 is widely used for over-voltage protection in a wide range of applications, such as automotive, aerospace, communication, industrial, and consumer electronics. The device can be used to protect sensitive electronic components from overvoltage events caused by lightning, EMI storms, and surge events. It is an ideal overvoltage protection device for applications where high clamping voltages and low capacitance are required.
