Introduction to TVS-Diodes

Transient Voltage Suppression (TVS) diodes are used to protect sensitive electronics form electrical surge damage. They work similarly to a regular diode, except with added protection from electrical surges. They are made up of two or more diodes that clamp the voltage to a certain rating. The amount of current that can be safely passed through is usually not limited by the TVS diode. Developed in the mid- 1960s, TVS diodes have become an essential component in everything from consumer electronics to automotive and military applications.

SM6T200AHE3/52 Application Field and Working Principle

The SM6T200AHE3/52 is a thyristor-based TVS diode from Semtech Corporation. It was designed for EOS and ESD protection, and has peak surge current rating up to 300A. This TVS diode can also be used in other applications, such as for HBM ESD immunity testing for automotive applications.The SM6T200AHE3/52 features a dual configuration of a silicon-controlled rectifier (SCR) and a TVS diode. This gives it excellent surge protection, even in high peak currents or long-lasting surges. The SCR component clamps the voltage during a surge, while the TVS diode part absorbs all the excess energy. The TVS diode also features a built-in damper network that ensures fast response times and minimal losses throughout the process. This helps to preserve equipment from any catastrophic damage resulting from the surge. The SM6T200AHE3/52 is made of an epoxy-coated ceramic package with an all-silicon molded body. It offers superior RF shielding and low mutual inductance. These features make it an ideal solution for highly sensitive RF applications. Thanks to its low leakage current ratings, the SM6T200AHE3/52 offers superior thermal stability and can handle extremely high temperatures without any significant voltage drop. It also offers protection against lightning strikes, reducing the risk of equipment damage or malfunction.In conclusion, the SM6T200AHE3/52 is a TVS diode specifically designed for EOS and ESD protection. It features a dual configuration of a silicon-controlled rectifier (SCR) and a TVS diode, providing superior surge protection even in high peak currents or long-lasting surges. It also features a built-in damper network for fast response times, an epoxy-coated ceramic package, and low mutual inductance, making it an ideal solution for RF applications. The SM6T200AHE3/52 can also handle extremely high temperatures and offers protection against lightning strikes.
