TVS-Diodes have been increasingly used in a variety of applications, such as data transmission, over-voltage surge and ESD protection, low capacitance bus clamping, signal reflection and other protective purposes. The SMCJ75ATR is an ultra-low capacitance TVS-Diode for high speed signal protection purposes.

The SMCJ75ATR is an unidirectional TVS-Diode that can be used for protecting high speed data transmission lines from damage due to electrostatic discharge (ESD) events. It is rated to absorb up to 8A of ESD current in less than 10ns. The SMCJ75ATR is constructed using a Central Semiconductor\'s proprietary SON (Silicon on Nitride) process, which enables low capacitance in a robust package.

The TVS-Diode consists of a central diode connected to two outer pins for connection to the data transmission line\'s ground. The two outer pins are used to measure the capacitance of the diode relative to the ground. The central diode is composed of two diodes connected in reverse parallel, which increases the reverse breakdown voltage of the device and makes it suitable for voltage spikes up to 400 volts.

The SMCJ75ATR works by diverting over-voltage transient energy away from the data transmission line. When an ESD event occurs, the voltage on the data transmission line increases rapidly. This voltage surge is then redirected to the two outer pins of the SMCJ75ATR, thus diverting the energy away from the data line. The SMCJ75ATR also clamps the voltage on the data line to a safe level, preventing damage from high voltage transients.

The TVS-Diode can be used in a variety of applications. It is most commonly used in high speed serial bus systems, such as Ethernet, USB, HDMI, and other types of data transmission protocols. It can also be used for ESD protection of automotive systems, such as airbag circuits, and in other electronics applications. The SMCJ75ATR is an ideal choice for protecting data transmission lines from ESD events as it has low capacitance and is robust and reliable.

In conclusion, the SMCJ75ATR is an ultra-low capacitance TVS-Diode for high speed signal protection. It is well suited for protecting data transmission lines from ESD events by diverting the transient energy away from the data line. The SMCJ75ATR can also be used for protecting automotive systems from ESD, as well as other electronics applications. The TVS-Diode is robust and reliable, making it an ideal choice for high speed serial bus systems and other data transmission protocols.
