TVS - Diodes are a class of semiconductor devices used to protect electronic components from over-voltage or electrostatic discharge (ESD). An over-voltage event is defined as either a positive or negative voltage spike that is higher than what a device is designed to withstand. ESD refers to the sudden release of static electricity, from either a person or an object, which could damage a device. The MPLAD30KP200A is a TVS diode designed to protect high-power I/O ports from over-voltage and ESD damage.

The MPLAD30KP200A is a surface-mount multilayer diode (SMD) component with a peak power rating of 10kW and a surge current rating of 30A. It is comprised of four distinct parts: anodes, cathodes, shield, and capacitors. The anodes and cathodes are connected at the package lead frame, which isolates two anodes and two cathodes within a single body. The shield, which is typically a layer of metal, protects the I/O port, and the capacitors reduce noise and stabilize the device’s voltage output.

The MPLAD30KP200A is designed for use in a variety of applications. It can be used in communication systems, industrial automation, and consumer electronics. It is typically used to protect high power I/O ports from over-voltage transients, ESD, and noise. In addition, it can be used to protect against over-current surges as well as lightning-induced over-voltages.

The MPLAD30KP200A works by forming a low capacitance “chain” between the anodes and the cathodes. When an over-voltage or ESD event occurs, the diode conducts current along the chain. The capacitors function as a buffer between the anodes and cathodes, which prevents harmful currents from flowing back to the I/O port.

The capacitors also act to reduce EMI (electromagnetic interference) noise, which is generated when current is conducted along the chain. This helps ensure that the device meets stringent EMI standards, such as ICES-003. The shield also helps to protect against EMI by preventing the current from flowing to the I/O port.

The MPLAD30KP200A is designed for higher reliability and durability, and has a low failure rate. The device is designed to meet stringent international standards, including AEC-Q101. In addition, the device is qualified for industrial and automotive applications.

In summary, the MPLAD30KP200A is a surface-mount TVS diode designed to protect high power I/O ports from over-voltage transients, ESD, noise, and over-current surges. It is designed for high reliability and durability, and is qualified to meet stringent international standards.
