TVS - Diodes

Transient-voltage-suppression (TVS) devices are built to provide robust overvoltage protection for sensitive electronics and system components. TVS diodes are designed to protect against transient voltages caused by lightning and other high-voltage events. They do this by conducting current away from vulnerable electronic components and diverting it harmlessly to ground (GND).The ESD9M5.0ST5G is a type of 5.0V uni-directional TVS diode, which is a state-of-the-art thyristor-based silicon protection device. This device is optimized for electrostatic discharge (ESD) and is designed to provide protection from electrical overstress in electronic systems.

Application Field

The ESD9M5.0ST5G is ideal for ESD protection of high-speed data lines such as USB, ULPI, and SATA data buses. Due to its 5.0 V breakdown voltage and 5.0 V clamping voltage, it is well suited for protection of cost-sensitive single-ended application buses and signal lines of computers, communication, consumer electronics, or automotive applications. Additionally, the device is UL recognized and can dissipate up to 11.9 W.

Working Principle

The ESD9M5.0ST5G is a TVS diode, which works by providing a current path for any transient voltage surge that is higher than the rated breakdown voltage of the diode. When this voltage appears on the protected line, the TVS diode starts conducting current and diverts the voltage away from the system to ground, protecting it from damage.The ESD9M5.0ST5G features a low clamping voltage, fast response times and a low insertion capacity, which helps to prevent any malfunction of the protected device combined with low power consumption. Additionally, the device is designed to handle extreme operating conditions such as mechanical vibrations, elevated temperatures, high humidity and strain at the connection points.

Conclusion

TVS diodes like the ESD9M5.0ST5G provide robust protection from transient voltages caused by lightning and other high-voltage events. They are designed to provide protection from electrical overstress in electronic systems, while offering a low clamping voltage, fast response times and a low insertion capacity. The device also features UL recognition and is ideal for the protection of highspeed, cost-sensitive applications.
