AOZ8235DI is a kind of Transient Voltage Suppressor (TVS) diode component. It is designed to protect sensitive electronics from high voltage transients. It is a bi-directional device, meaning it can protect against positive and negative voltage transients, by effectively clamping the voltage above or below a predefined safe limit.

AOZ8235DI\'s application field mainly involves communication, computer system, consumer electronics, industrial control systems, automotive circuitry and other electronics that need transient voltage protection. Its application scenarios include protecting IC from ESD (electrostatic discharge), protecting power supplies from over-voltage transients, protecting communication lines from EFT (electrical fast transient) and protecting electrical components from surges and inductive load switching.

The core principle behind this diode component is its ability to dissipate and absorb energy from surge events, lightning strikes and other high-voltage transients, shielding the connected component from damage. It is designed to be used after a standard protect that has current limited, which is usually accomplished by a fuse, positive temperature coefficient resistor, transistor or some other component.

AOZ8235DI typically consist of a zener diode or a bipolar junction transistor connected in a reverse series connection. The zener diode voltage drop is designed to develop a voltage, and the reverse breakdown voltage of the zener diode is usually designed close to the maximum allowed operating voltage of the component that it is connected to, assuring that any excess voltage will be absorbed by the zener diode instead of passing through the sensitive circuit.

Apart from the zener diode, a bidirectional TVS diode also consists of three layers of alternating PN materials, which act as a surge absorbing element. In case of a surge, the alternated PN layers generate a large avalanche start up current that causes the diode to \'switch\' from a high resistance OFF state to a low resistance ON state. Each AOZ8235DI diode component is rated with a peak pulse power, maximum clamping voltage and surge current specifications.

In conclusion, AOZ8235DI is a kind of TVS diode component, mainly used in communication, computer system, consumer electronics, industrial control systems, automotive circuitry and other electronics that need transient voltage protection. Its main function is to protect sensitive electronics from high voltage transients. It consists of a zener diode connected in a reverse series connection, together with three layers of alternating PN materials, that act as surge absorbing elements. Each AOZ8235DI diode is rated with a peak pulse power, maximum clamping voltage and surge current specifications.
