MXP4KE24AE3 Circuit Protection

MXP4KE24AE3 is an advanced Transient Voltage Suppression (TVS) diode protection device. Equipped with a voltage regulator, it not only protects the system from transient over-voltage events such as electrostatic discharge (ESD) or electrical fast transients (EFT), but also gets rid of the need for an external low-pass filter. This makes it an ideal choice for protecting high-speed digital lines and sensitive analog lines from voltage transients.

Application Field

The MXP4KE24AE3 is a voltage regulator designed to protect data lines from voltage transients. It can protect not only parallel data buses, but also high speed point-to-point interfaces (e.g. HDMI, USB, DisplayPort), usually connected at a point near the middle of the signal line, as well as cables that have to be routed across multiple pieces of electronics. It can also be used in medical devices, smartphones, watches and many other high-end products that need to have high immunity against transient voltages.

Working Principle

The MXP4KE24AE3 works by clamping the output voltage within a specific range. It contains two transistors (one P-type and one N-type), in between which a Zener diode is connected. The transistors act as current sources that provide the necessary current to maintain the Zener diode\'s conduction. This way, even if an over-voltage transient event occurs, the Zener diode will be able to maintain the output voltage within a specified range, preventing any damage to the connected lines or circuits.

In addition, there is also an internal low-pass filter connected to the output of the MXP4KE24AE3, which helps to reduce the noise and ensure the integrity of the signal. This makes it a great choice for applications in which data rate is important.

Conclusion

The MXP4KE24AE3 is an advanced TVS diode designed to protect high-speed digital lines and sensitive analog lines from transient over-voltage events. It can also be used in medical devices, smartphones, watches and many other high-end products that need to have high immunity against transient voltages. Thanks to its internal low-pass filter, it is also suitable for applications in which data rate is important.
