The MAPLAD18KP90CAE3 is a high-speed surge protective device (SPD) with a Uni- and Bi-directional Transient Voltage Surge Suppressor (TVS-Diode) designed for the protection of various industrial and consumer electronics from transient voltage events. It also offers protection against Electrostatic Discharge (ESD) by providing a low-capacitance bidirectional ESD protection solution in addition to the TVS-Diode protection. In this article, we will explore the application fields and working principles of the MAPLAD18KP90CAE3.

Applications for MAPLAD18KP90CAE3

The MAPLAD18KP90CAE3 is ideal for industrial, automotive, communication, and consumer electronics. It provides fast response and low clamping voltage and is UL recognized for its safety and efficacy. It can be used for the protection of parallel I/O lines, protection of data/logic interfaces, memory protection, and serial communications.

In industrial applications, the MAPLAD18KP90CAE3 provides protection against overvoltage and transients which can cause product malfunction or even damage. It is particularly suitable for equipment and systems subjected to high levels of electrical noise in applications such as motors, automation, HVAC, lighting, heavy machinery, and so on. In automotive applications, the device is ideal for protection of onboard ECUs, sensors, actuators, and audio systems which must be effectively safeguarded against rapid power, transients, and voltage noise.

In the communication industry, the MAPLAD18KP90CAE3 is suitable for protecting high-speed signals from overvoltage and transients. This includes the protection of Ethernet and USB ports and lines in networking and communications equipment, as well as the protection of optical components and high-speed signal interfaces.

The MAPLAD18KP90CAE3 is also suitable for consumer electronics such as small computing platforms, set-top boxes, and gaming consoles. Its low capacitance and fast response time make it ideal for the protection of high frequency signal lines in a wide range of consumer products.

Working Principle of MAPLAD18KP90CAE3

The MAPLAD18KP90CAE3 is based on a Transient Voltage Surge Suppressor (TVS-Diode) which is designed to provide protection against overvoltage transients and fast transient events. The device is configured to provide a clamping voltage which is lower than the maximum rated voltage for the equipment being protected, thus ensuring maximum protection without causing any damage to the protected equipment.

The TVS-Diode operates by switching between high- and low-impedance states when triggered by a transient voltage. When the voltage exceeds the breakdown voltage of the diode, the diode switches to a high-impedance state and provides a low resistance path between the signal and power lines, diverting the unwanted current away from the equipment. When the voltage returns to normal, the diode switches back to its low-impedance state, allowing the signals to return to their original paths.

The MAPLAD18KP90CAE3 also features a high-performance ESD protection circuit which works in conjunction with the TVS-Diode to provide comprehensive protection against voltage and ESD transients. The ESD protection circuit is designed to provide fast response to ESD events and is capable of handling up to eight kilovolts of ESD.
