MXPLAD18KP24AE3 application field and working principle

TVS diodes or Transient Voltage Suppression Diodes are protective devices used to protect electronics and circuit boards from high-voltage transients such as those caused by lightning strikes or power surges. The MXPLAD18KP24AE3 is one of the most widely used devices in this category. It is designed to protect data lines from overvoltages and can be used in a variety of applications from industrial and automotive to consumer electronics.

Application Field

The MXPLAD18KP24AE3 is ideal for applications where high voltage transients can occur, such as automotive, industrial, medical, consumer electronics, telecommunications, and other fields. This device is capable of protecting one or more data lines from transients in the range of 22 to 24 Volts. It offers excellent ESD protection for up to 15KV of human body model (ESDHBM) and 8KV of machine model (ESDMN) discharge. Furthermore, it also provides a high-efficient protection for up to 10A of peak current and IEC 61000-4-2 (ESD) up to 8KV for air discharge and 5KV for contact discharge as per IEC 61000- 4-2.

In automotive and industrial applications, the MXPLAD18KP24AE3 is designed to protect systems from transients caused by lightning strikes. It is also used to protect automotive ECUs, CAN/LIN networks, and automotive power cables. In the medical field it is often used for protection against ESD and ESD transients, and in consumer electronics for protection of data lines from overvoltage transients.

Working Principle

The MXPLAD18KP24AE3 is a TVS diode based on Zener diode, avalanche breakdown or surface channel technologies to provide excellent transient voltage suppression (TVS) protection. Zener diodes offer excellent protection in cases where the transient voltage exceeds the clamping voltage, which is determined by the Zener voltage of the diode. Avalanche breakdown technology is used when the reverse breakdown voltage is above the Zener voltage and is capable of handling transients up to several hundred volts. The surface channel technology is used for higher voltage levels, and can offer ESD protection up to several thousand volts.

The MXPLAD18KP24AE3 features a low on-state resistance of 18 milliohms, allowing for high-speed switching with minimal power dissipation. It has a peak pulse power rating of 1000 watts, which means it can handle transient voltages up to 24V without damage. Furthermore, it allows for a high peak current rating of 10A, making it suitable for a wide range of applications.

The MXPLAD18KP24AE3 is equipped with a built-in thermal protection circuit to protect itself from damage due to overheating. It also features an advanced soft-clamping technology that reduces IEC600 61000-4-2 ESD stress events. This technology utilizes a soft clamping network which adjusts the device\'s voltage level to protect the connected circuit from overvoltage transients.

In summary, the MXPLAD18KP24AE3 is a highly reliable TVS diode designed to protect circuit boards and electronic components from overvoltage transients. It can be used in a wide range of applications from automotive to medical to consumer electronics, and is capable of supporting data lines up to 24 volts.
