The AQ3045-01ETG is a part of the TVS – Diode family and it can provide effective protection against voltage transients like electrostatic discharge. It is also known as Transil or Transient Voltage Suppressor (TVS). TVS Diodes are both unidirectional and bidirectional components that suppress voltage transients which are generated due to a wide variety of sources such as electrostatic discharges (ESD), inductive load switching or lightning.

AQ3045-01ETG component offers various advantages like improved performance in electrostatic discharge protection (ESD) up to 20kV (contact) and 30kV (air), smaller size, low capacitance and low leakage current. It can also work over a broad temperature range of -55°C to +125°C.

AQ3045-01ETG Application Field

AQ3045-01ETG is mainly used in applications where you expect to see strong current transients, like automotive systems, consumer electronics, industrial, medical and military systems. The AQ3045-01ETG is also used in situations where you need a good level of noise protection along with heavy surges, such as in residential security systems, access control systems, and lighting systems. It is also widely used in instrumentation and computing systems, renewable energy systems, and automotive audio systems among others.

AQ3045-01ETG Work Principle

AQ3045-01ETG has a metal oxide-based, low capacitance body structure with a very fast switching response. The device is able to dissipate energy without relying on the circuit’s ground path by having an active electrode connected to the positive line of the circuit. This makes it ideal for applications that require fast protection from large and unwanted electrostatic discharges. The AQ3045-01ETG is also an environment degreaser, meaning it can self-degrease when exposed to heat.

When the device is exposed to a large voltage transient, a high-speed avalanche breakdown occurs between the anode and cathode. This causes current to move from the anode to the cathode. When current flows, the device seeks its equilibrium state and suppresses the overvoltage or spike within a short period of time. As the current surge subsides, the device automatically decays to its ground state.

The AQ3045-01ETG device also features one thousand volts of reverse stand off voltage and 32V maximum clamping voltage. It is designed to be able to handle current peaks of up to 2A and has an operating temperature range of -55°C to +125°C. Such features make it uniquely suitable for high energy transient protection.

In conclusion, the AQ3045-01ETG belongs to the TVS Diode family and is mainly used in applications where you need a fast-acting protection from large electrostatic discharges like automotive systems, consumer electronics, and industrial applications. It can handle current surges up to 2A and has a very fast response time. Moreover, it can provide environment degreasing and offers up to 30kV of protection against air static discharges.
