TVS diodes are specially designed transistors that protect other components in the circuit. These diodes provide protection against damage from electrical surges such as electrostatic discharge (ESD) or lightning. The SA30A-E3/73 is a TVS diode designed to protect electronics from overvoltage. It is an ultra-low capacitance integrated ESD and transients protection device containing four bilateral triggering diodes in one package.

SA30A-E3/73 Application Field

The SA30A-E3/73 is a low capacitance, low-cost overvoltage protection diode suitable for ultra high-speed I/O ports used in electronic data communications systems. It is ideal for protecting high frequency signals in applications such as USB 3.0, Firewire, Ethernet, and other high speed serial data lines. It also provides excellent protection against ESD, mis-wiring, and power surges. The SA30A-E3/73 is commonly used in automotive, industrial, networking, consumer, and medical applications.

SA30A-E3/73 Working Principle

When an overvoltage is applied to the diode, the built-in circuit inside the SA30A-E3/73 senses the voltage and triggers the diode. Once the diode is activated, the diode conducts current which causes the voltage on the protected line to drop and safely dissipate the excess energy. This prevents damage to any connected components. The diode is then reset and ready for use again. The SA30A-E3/73 can handle up to 20A of current and provides high surge current capability, making it ideal for protecting sensitive electronic components from overvoltage.

Conclusion

The SA30A-E3/73 is a low-cost, low capacitance overvoltage protection diode that is suitable for use in a variety of applications. It is ideal for protecting high frequency signals in applications such as USB 3.0, Firewire, Ethernet, and other high speed serial data lines. It provides excellent protection against ESD, mis-wiring, and power surges. The SA30A-E3/73 is an important component in any system that requires protection from overvoltage damage.
