TVS - Diodes: SMCJ200CAE3/TR13 Application Field and Working Principle

The SMCJ200CAE3/TR13 is a bi-directional transient-voltage-suppression (TVS) diode that is designed to protect sensitive integrated circuits and voltage passages exposed to high voltage transients. As part of the TVS diode family, the SMCJ200CAE3/TR13 is designed to provide fast clamping and excellent energy handling capability. This device is optimized for unidirectional suppression of transients and is designed to replace data line protection applications.

Application Field

The SMCJ200CAE3/TR13 bi-directional TVS diode is used as an ultrafast-clamping device for overvoltage events such as electrostatic discharge (ESD), electrical fast transients (EFTs), lightning events, and inductive loads. It is ideal for protecting communication lines such as Ethernet, USB, and high-resolution video. It can also be used for protection of I/O interconnects during testing and in I/O port protection applications.

Working Principle

The SMCJ200CAE3/TR13 is a bi-directional Transient Voltage Suppression (TVS) diode array with an integrated ESD protection circuit. The diode array consists of two mutually coupled diodes with an integrated ESD protection circuit. The two diodes are operated in opposite directions to provide a fast response time to overvoltage events. The integrated ESD protection circuit is designed to provide an integrated field effect transistor (FET) switch, with a diode clamp, to ensure a fast response to ESD events. The diode array is designed to provide an overvoltage protection of up to 200V.

The device is designed to reduce voltage transients on data lines by utilizing the two diodes to quickly clamp and reduce the voltage when an overvoltage event occurs. The ESD protection circuit shuts off the input and output when an ESD event occurs, ensuring protection of the device from ESD.

The TVS diode also features a low breakdown voltage and low reverse leakage current, which provides for an efficient response to overvoltage transients. The TVS diode can be used for both unidirectional and bidirectional overvoltage protection applications. Additionally, the diode can be used for overvoltage protection of sensitive integrated circuits.

Conclusion

The SMCJ200CAE3/TR13 bi-directional TVS diode is an ideal solution for protecting sensitive components against overvoltage events. With its integrated ESD protection circuit and fast response time, the TVS diode is suitable for applications such as Ethernet, USB, and high-resolution video. This device is optimized for unidirectional suppression of transients and is designed to provide an overvoltage protection of up to 200V.
