TVS diodes, also known as Transient Voltage Suppressors, offer protection from damaging voltage transients caused by electrostatic discharge, as well as from surges or other causes of overvoltage. The specification of these devices is critical, as they must be carefully chosen according to the voltage, current, power and other electrical characteristics. MXPLAD18KP85AE3 is a type TVS diode that is widely used in various applications.

MXPLAD18KP85AE3 is a unidirectional TLCP-powered diode designed to provide overvoltage protection from destructive electrical transients. It features an proven, low leakage current design that operates at -55°C to +125°C junction temperature. Its capability includes a maximum operating peak Pulse Power of 1.2KW (10/1000µs) and breakdown voltage from 5.8V to 18KV (range is 4.75V to 20KV, actual test range is 5.8V to 18KV). This device has bidirectional electrostatic discharge (ESD) protection within a small surface mount package. As an alternative to standard zener diode, this part has a superior clamping capability.

MXPLAD18KP85AE3 is a compact solution for broadband ESD protection for data lines, and can be used in almost any small form factor electronic device. It is suitable for protection in telecommunication, networking and industrial electronics. Its overvoltage protection capabilities make it suitable for protecting automotive electronics systems from electrical transients due to load dump, battery discharge, and other threats. Additionally, it is widely used in USB ports, RS232, and other I/O ports where transient protection is needed.

The working principle of MXPLAD18KP85AE3 is based on the Avalanche Breakdown principle. When the applied voltage exceeds the peak inverse voltage (PIV) of the diode, the electric field in the depletion region of the diode exceeds the dielectric strength of the junction. This causes the PN junction to become highly conductive, creating a highly visible current pulse. This keeps the voltage across the diode at a breakdown voltage level, preventing destruction of the components.

In conclusion, MXPLAD18KP85AE3 offers superior ESD protection for industrial, telecom and networking applications, with fast response time and low leakage current. Its electric field based technology enables it to offer successful protection from voltage transients and provide surge protection against load dump and other threats. It is cost-effective and easy-to-use making it a popular choice for protecting electronic circuitry.
