MP4KE400AE3

TVS - Diodes are designed to protect sensitive electronic equipment against voltage spikes from lightning, high-powered transmitters, or inductive switching loads. The MP4KE400AE3 is a type of TVS - Diode component manufactured by STMicroelectronics, specifically designed for use in negative voltage scenarios. The MP4KE400AE3 is a 400 watt, 400 volt bidirectional transient voltage suppressor component.

The primary application fields of the MP4KE400AE3 include power electronics, port protection, power supplies, automotive, consumer and communication electronics. It can be used to protect power, data, USB and LAN connectors, and other high power or voltage sensitive components. This component is also fully RoHS compliant, making it suitable for all types of environmentally friendly applications.

The MP4KE400AE3 offers low power loss, fast response times, and good thermal stability. It is an efficient and reliable way to control voltage transients. The component is designed to absorb any excess voltage from an electrical supply, protecting circuits from damaging voltages exceeding their working parameters. The MP4KE400AE3 acts as an active protection component and can be configured to absorb up to 400 watts of energy in the event of a voltage spike or surge.

In terms of working principle, the MP4KE400AE3 is designed to quickly clamp excess voltages at levels lower than its breakdown. When the voltage reaches the breakdown level, the device will conduct current, shifting its electrical characteristics to limit it to acceptable levels. This clamps the voltage at a predetermined level, allowing normal operation to be resumed and protecting other components from damage.

When this component is used, it is connected in series with the other electrical circuit to be protected. Once the surge voltage has been clamped, it is safely dissipated across the components, developing a controlled flow of power which can be easily managed. This helps to prevent any component damage or data corruption as the voltage is diverted into a safe current path.

The MP4KE400AE3 is a robust device designed to protect sensitive components. Its response time is faster than standard spark gap devices, allowing it to react almost instantaneously to excess voltage. This makes it a reliable and effective way to protect against voltage transients. The device is also simple to use and easy to integrate into any electrical circuit, making it a popular choice amongst engineers.
