AOZ8211DI-05 is a rated unidirectional transient voltage suppressor diode chip with a particular operating voltage. The chip is classified under the TVS – Diodes, due to its characteristics of suppressing voltage transients on power lines. The chip limits the voltage transients in power line applications, thus protecting vulnerable components on the power lines from damage either from Electro Static Discharge (ESD) or Electrical Fast Transients (EFT).

AOZ8211DI-05 is designed as a low-capacitance device, specifically to secure the high-speed digital data interface of I/O ports in personal computers, peripherals and other equipment. It has a low maximum leakage of 400 nA at an operating voltage of 5V. This diode chip is available in a variety of packages, including dual in-line packages (DIPs), small out-line packages (SOPs) and so on, to suit the requirements of the application.

The working principle of the AOZ8211DI-05 diode chip is that of a voltage source. The device is designed to draw current, when the input voltage rises above the breakdown voltage. Thus, when a positive voltage is applied to the anode of the diode chip, current flows from the anode to the cathode when the voltage reaches the breakdown voltage of the diode. This current is proportional to the voltage applied. When the current reaches a certain level, the diode will switch off, stopping the flow of current.

The AOZ8211DI-05 transient voltage suppressor diode chip finds its major application in power line protection. It provides protection from ESD and EFT transients on power lines. This is done by clamping the voltage at a certain level, thus limiting the rise of voltage. This ensures that the vulnerable components on the power line, like the delicate internal circuits of a computer, are protected from power surges caused due to ESD or EFT pulses.

Apart from power line protection, the AOZ8211DI-05 transient voltage suppressor diode chip finds application in other areas also. Some of these are signal line protection, suppression of inductive spikes in switching power supplies, automotive electronics and so on. Therefore, this diode chip is a versatile device that finds wide application in various electronics, power transmission and automotive industries.
