TVS- Diodes

Transient Voltage Suppressors (TVS) diodes are protective devices that provide over voltage protection for various types of electronics, such as notebooks, phones, displays, etc. The MXLPLAD18KP30AE3, a model in a series of low-capacitance TVS diodes with a working voltage range of 5.5 to 18V, is suitable for IEC 61000-4-2 based system protection form ESD, EFT and surge. This article will discuss the key properties, application field and working principle of MXLPLAD18KP30AE3.

Key Properties

The MXLPLAD18KP30 is one of the latest generation of low-capacitance, high-speed TVS diodes.It offers ESD protection with IEC 61000-4-2 compliance and can sustain an ESD shock wave of up to 30kV contact discharge. Its surge protection with IEC 61000-4-5 compliance has an 8/20μs pulse wave capable of withstanding a surge up to 30A. The MXLPLAD18KP30 is an ultra-low capacitance device, with a capacitance of only 0.44pF, which increases protection and does not affect the system’s normal operating speed. It can operate at a wide range of temperature, from - 50℃ to +125℃, and its clamping voltage is about 13V for a 5V system.

Application Field

The MXLPLAD18KP30 is ideal for protecting notebooks, phones, displays, etc. from ESD, EFT and surge. It provides protection for the system’s electrical components by diverting hazardous voltages away from delicate circuitry. The low-capacitance ESD protection of this device makes it perfect for protecting data lines from ESD and EFT transients. The diodes can be applied to data and signal lines exposed to the outside environment, such as USB ports, PCMCIA connectors, Ethernet cables, etc.

Working Principle

TVS diodes are designed to be bi-directional, meaning that they can be either electrostatically or thermally charged in reverse bias. When a voltage greater than the trigger voltage is applied to the diode, the diode starts to conduct current, transferring the surge energy to the ground. This process will create a window of clamping voltage, which limits the voltage that can reach the protected device. The low capacitance of the MXLPLAD18KP30 makes it an ideal choice for protecting data lines from ESD and EFT transients. The diode can be used on data and signal lines and will protect the system’s electrical components from voltage fluctuations. The diodes are also designed to dissipate heat quickly, ensuring that they don’t become too hot and cause any malfunction in the system.

Conclusion

The MXLPLAD18KP30 is an ultra-low-capacitance TVS diode with a wide working voltage range suitable for protecting systems from ESD, EFT, and surge. It is ideal for protecting notebooks, phones, displays, and other electronic products from voltage fluctuations. The diode’s intrinsic features, such as its low capacitance and high surge protection, make it perfect for protecting high-speed data and signal lines. Furthermore, the wide temperature range and its ability to quickly dissipate heat provide increased stability and peace of mind when using this product.
