It also has a low capacitance of 0.5pF making it suitable for high speed signal and data lines where low capacitance is essential. The diode\'s current handling capabilities are impressive for its size - it can handle peak pulse currents of up to 10.8A and its peak working power is 400 watts.

In terms of application fields, the MXSMCJ85AE3 is suitable to provide protection to telecom lines, LAN interfaces, signal lines and sensitive power supplies. It also finds use in a variety of industrial applications such as power switching applications, motor control circuits and generator overvoltage protection.

The working principle of the MXSMCJ85AE3 is relatively simple. The device is designed to be a protective barrier, using its low capacitance silicon junction to limit the current flow to a safe level. When a voltage transient exceeding the breakdown voltage of the diode\'s Zener diode occurs, the junction\'s low capacitance allows for a high rate of current increase, while the Zener diode helps clamp the voltage to a safe level ensuring there is no damage to the circuit.

The diode\'s bidirectional characteristics also ensures that it does not have to be installed with a specific polarity, allowing for even greater flexibility of installation.

The MXSMCJ85AE3 is one of many TVS - diodes available today. It offers a wide range of applications, low capacitance, high power handling capabilities and bidirectional protection. Its low capacitance silicon junction and Zener diode combination provide unsurpassed protection against high voltage transients, making it an ideal application in the telecommunications, computer and industrial industries.
