MP4KE7.5AE3

TVS (transient voltage suppressor) diodes are an important component in protecting circuits from voltage transients, spikes, and other electrical surges. The MP4KE7.5AE3 TVS diode is designed for protection against voltage transients in medium to high voltage applications. In this article, we’ll discuss the application fields and working principle of the MP4KE7.5AE3 TVS diode.

Application Field

The MP4KE7.5AE3 diode is designed for medium to high voltage applications, with a maximum operating voltage of 7.5V and a breakdown voltage of 8.1V. It is suitable for a wide range of applications, such as automotive, industrial, and telecom. The diode is designed to protect against surges and transients, as well as providing excellent protection against ESD (electrostatic discharge).

The MP4KE7.5AE3 diode is also designed for low power loss, with a reverse leakage current of less than 20mA at 20V. This low current level helps ensure the efficient operation of the device and helps reduce power consumption. The diode also has excellent thermal stability, allowing it to operate at high temperatures without compromising its performance.

The diode is also designed for low leakage, with a maximum leakage current of 10μA. This low leakage helps ensure that the device operates in an energy-efficient manner, while also helping to protect against overvoltage events.

Working Principle

The MP4KE7.5AE3 diode is designed to protect against voltage transients and spikes. The diode contains a Zener diode integrated with a varistor, which allows the device to block any voltage transients or surges that may occur. The diode also contains a clamp circuit, which prevents the device from continuing to conduct current once the transient or surge has been blocked.

In operation, the diode senses when the voltage transients or spikes reach a certain level. When this level is reached, the diode will conduct current and the transient or spike will be blocked. This prevents the device or circuit from undergoing any damage due to the voltage surge or transient. When the transient or surge has been blocked, the diode will cease to conduct and will return to its low power state.

The MP4KE7.5AE3 diode is a highly reliable and efficient device, capable of protecting circuits from voltage transients and spikes. The diode is suitable for a wide range of applications, and is designed for low power consumption and high thermal stability. The diode’s working principle is based on the use of a Zener diode and a varistor, as well as a clamp circuit to prevent current conduction once the transient or surge has been blocked.
