AQ1003-01ETG Circuit Protection

Transient Voltage Suppressors (TVSs) are electrical protection components that limit the voltage at the devices to a manageable level, normally between 3V and 200V. TVSs are typically used in electronics and automotive systems, to protect against dangerous voltage spikes, power surges, over-voltage, and over-current events. The AQ1003-01ETG is an example of a TVS device that has been designed for use in a wide range of applications. This article will discuss the application field and working principle of the AQ1003-01ETG.

Application Field for the AQ1003-01ETG

The AQ1003-01ETG is a bi-directional TVS device that is typically used for protecting high-power digital systems against electrostatic discharge (ESD) and other transient events. The device is used in a variety of applications, including automotive, consumer electronics, telecommunications, and industrial systems. The AQ1003-01ETG is designed to protect against a wide range of voltages, from 3V to 200V, and is suitable for use in a variety of operating temperatures, from -55°C to +150°C.

The AQ1003-01ETG is also suitable for use in a range of high-power digital systems. It is capable of handling currents up to 4A, making it ideal for high-power applications such as motor controllers, charging systems, and other similar devices. The device also features a very low clamping voltage (Vcl), which allows it to be used in sensitive applications where a low clamping voltage is required.

Working Principle of the AQ1003-01ETG

The AQ1003-01ETG utilizes a common flyback diode configuration that is commonly used in TVSs. This type of TVS device works by clamping the voltage at a safe level, usually between 3V and 200V. When the input voltage (Vin) rises above the device’s clamping voltage (Vcl), the device will start to conduct current. This current flow will create a voltage drop across the device, limiting the voltage at the output (Vout) to Vcl.

The AQ1003-01ETG features a fast acting response time, allowing it to quickly clamp voltage spikes and protect the system from damage. The device is also capable of handling high peak currents and can dissipate up to 1.9W of power. This makes it ideal for use in high-power, fast-switching applications.

Conclusion

The AQ1003-01ETG is a bi-directional TVS device that is specifically designed for use in high-power, fast-switching applications. It is capable of clamping voltages between 3V and 200V and can handle peak currents up to 4A.
