AQ3118-01ETG

TVS (Transient Voltage Suppressors) diodes, also known as protective diodes or spike suppressors, are used to shield a wide range of electrical and electronic components from damage due to transient surges and spikes that can occur in power supplies or data lines. The AQ3118-01ETG is a type of TVS diode designed to provide protection against high-voltage transients. In this article, we will discuss the application field and working principle of the AQ3118-01ETG in detail.

Application Field of AQ3118-01ETG

The AQ3118-01ETG is part of a two-line TVS family that provides a high level of protection from transient over-voltage. It has a low capacitance allowing it to be used for ESD protection in electronic devices such as sensors, PCs, communications equipment and audio equipment. It has an adjustable peak-pulse capability up to 16A at 8/20 μs for various levels of surge protection. It also has a wide operating voltage range of -6.5V to +17V. The device is capable of protecting two lines from damage due to a surge or a spike in power or data lines.

Working Principle of AQ3118-01ETG

The AQ3118-01ETG is designed to provide a high level of protection from over-voltage transients by responding quickly to surges and spikes. It features an integrated Zener diode and a low capacitance bi-directional MOSFET-controlled switch for protection of two lines against over-voltage transients. The integrated Zener diode serves to clamp down and dissipate high-energy surges as heat, while the low capacitance MOSFET-controlled switch acts as a mechanical switch that gets activated when the line voltage exceeds a certain level. When it is activated, the kinetic energy within the voltage surge is dissipated quickly and harmlessly before the line voltage can reach a damaging level.

Conclusion

The AQ3118-01ETG is a versatile type of TVS diode designed to provide protection against high-voltage transients. It features an integrated Zener diode and a low-cap MOSFET-controlled switch for protection of two lines against over-voltage transients. It is designed to be used in applications such as PCs, communications equipment and audio equipment. The AQ3118-01ETG is a great choice for those looking for a reliable and effective way to protect electronic components from over-voltage transients.
