TVS-Diodes Overview

TVS-diodes are specially designed transistors used to protect sensitive electronic circuits, such as telephone lines, from over-voltage transients. The TVS diode consists of a semiconductor junction with internal components designed to shunt the excess current away from the sensitive circuitry when voltage exceeds a certain threshold.

To protect a given line or device, the TVS diode must be able to absorb a given energy (as a function of current and voltage, expressed as "I²t") and provide the necessary surge protection while maintaining a low capacitance to the device. TVS-diodes typically come in various voltage ratings, and several types of packages to fit all kinds of applications.

TV02W400B-G Application Field and Working Principle

The TV02W400B-G TVS diode is designed to offer surge protection in low-speed data communications applications, such as modem connections and ETHERNET cable runs. It is also well-suited for protecting low power analog circuits used in telephones and fax machines. With its 100V breakdown voltage, the TV02W400B-G is a suitable choice for providing surge protection in Ethernet cable runs.

The TV02W400B-G TVS diode works by limiting current to the device when a voltage greater than its breakdown voltage is applied. The diode has an open circuit voltage of up to 100V and a breakdown voltage of 110V, with a maximum surge rating of 800A. The response time of the diode is typically less than 1ns, making it well-suited for data line protection.

The device is made up of a special material layer integrated into a semiconductor substrate. The material layer offers bidirectional protection, and its fast response time is well-suited for data line protection. The TVS diode is available in different types of packages, including axial, radial, DO-35, and DSAF. Depending on the application, the TVS diode can be soldered directly to the board or mounted in a socket.

The TV02W400B-G is a good choice for protecting low-speed data lines, as it has low capacitance, fast response time, and can handle high levels of energy. Additionally, the TVS diode is RoHS compliant, making it an excellent choice for protecting sensitive electronic circuits.
