TVS – diodes are devices that protect sensitive electronics from transient voltage surges by suppressing the voltage to a safe level. One particular found in this family is the MOV-5KE170CAE3, made by Littelfuse. This device is a 5.0 kilovolt (kV) differential surface-mount TVS diode that is designed to protect high speed data lines from electrical overstress (EOS) and electromagnetic interference (EMI).

Application field and Working Principle

The MOV-5KE170CAE3 is particularly useful for high speed data lines in low may applications. It is rated for a maximum of 170 amperes (A) peak pulse current and has an impressive low clamping voltage of 58 volts (V).It is ideal for RS485 (TIA-485) computer ports, Gigabit Ethernet, Fibre Channel, USB, IEEE-1394 and other applications. It is also suitable for the CAN and LIN buses.

The MOV-5KE170CAE3 is designed to provide protection against overvoltage conditions caused by lightning and other sources of electrostatic discharge (ESD) and electrical fast transients (EFT). It is important to note that this device is not designed to protect against large, sustained voltage surges or high energy transients like those caused by inductive loads.

This TVS diode works through a simple but efficient mechanism. When an overvoltage condition arises, this diode will rapidly and safely conduct the current away from the protected circuit. The current is then clamped to a safe level, preventing the protected circuit from being damaged. This diode has a low capacitance of just 17pF, making it suitable for high speed data lines.

The MOV-5KE170CAE3 is also beneficial because of its ultra low leakage current. It is capable of conducting 350nA at 10V, which is of great benefit to applications that are sensitive to low levels of static leakage current.

The MOV-5KE170CAE3 is supplied in a do9s package which measures 2.64mm x 3mm x 0.85mm, and its low profile makes it easy to install. This device is RoHS compliant and highly reliable, with a total failure rate of lower than one incident per 100,000 hours.

In conclusion, the MOV-5KE170CAE3 is an exceptional choice for applications needing fast and efficient surge protection. It is reliable and highly robust, which makes it a great choice for protecting high speed data lines.
