The AOZ8245DI-05 is a TVS - Diodes which is a transient voltage suppression diode. It is second generation from AON that offers improved performance in a single component package. In other words, it is a two-polarized diode that clamps the voltage of positive and negative signal lines to a known and safe level. The device is rated for a peak pulse surge current up to 5.5A, having a breakdown voltage from 22V to 30V.

The AOZ8245DI-05 is designed to protect I/O ports, equipment, systems and power lines from the destructive forces of high-amplitude spikes generated from lightning and ESD. It also acts as a surge isolation device, used in combination with other surge protection components, to protect control panels and other vital equipment from extreme spike events due to transient conditions. The device comes in an SOT-23 SMD package and is RoHS-compliant and UL recognized.

The AOZ8245DI-05 can operate under both unidirectional and bidirectional operations, providing outstanding ESD protection performance. Under unidirectional operation, the diode conducts current only in the forward direction from the anode to the cathode; while under bidirectional operation, it conducts current in both directions, in which current is limited by the reverse breakdown voltage.

The AOZ8245DI-05 works by clamping the voltage of either the input or output signal line to a safe and known value, so as to prevent any damage to the system due to overvoltage stress. The working principle can be best described using the three-terminal diode model. Basically, the anode is connected to the input signal line while the cathode is connected to the output line. The breakdown voltage is typically between 22V and 30V, and when this level is reached, the diode will start to conduct current.

The AOZ8245DI-05 device is mainly used in various industrial, consumer, and automotive applications. For industrial applications, it is used to protect control systems from ESD and transients by providing efficient protection. It is also widely used in consumer electronics such as laptops, mobile phones, and TVs to provide voltage surge protection. Similarly, it can be used in automotive applications to protect critical ECU and data lines from electrostatic discharges and overvoltages.

In conclusion, the AOZ8245DI-05 is a transient voltage suppression diode which can protect electronic equipment, systems and power lines from destructive forces of high-amplitude spikes generated from lightning and ESD. It is most commonly used in industrial, consumer and automotive applications for providing efficient protection against voltage surges and electrostatic discharges. The device operates under both unidirectional and bidirectional operations, and comes in an SOT-23 SMD package that is RoHS-compliant and UL recognized.
