AOZ8105CI is a transient voltage suppressor (TVS) diode designed to protect electronic devices from destructive transient events. It is available in an ultra-miniature SOT-23 package for space-constrained applications, making it an ideal choice for protecting sensitive circuit components and interfaces from damages caused by lightning and fast transients in automotive, industrial, and consumer electronics.

The AOZ8105CI has a unidirectional configuration and reverse stand-off voltage of 8 Volts, with a peak pulse power rating of 400W. The diodes offer excellent clamping capability, extremely fast response time, and minimum transient overshoot. It has a reverse breakdown voltage of 8V and reverse current of 250 mA, enabling effective suppression of overvoltage transients.

The working principle of the AOZ8105CI is based on the avalanche breakdown phenomenon that takes place when the reverse voltage applied to the diode exceeds its rated breakdown voltage. When this happens, the diode begins to conduct in the reverse direction, dissipating a large amount of energy. This action reduces the over-voltage and current to a safe level, protecting the circuits downstream.

The AOZ8105CI can be used in a variety of applications, including automotive, industrial, consumer, and portable electronics. Automotive applications, for example, may include ignition, fuel injection, airbag, and parking sensor systems. Similarly, industrial applications include relay protection, DC/DC converters, telecom line cards, and medical equipment. The AOZ8105CI is also popular in consumer electronics, such as TV and set-top boxes, and in portable electronics like smartphones, tablets, and data logging solutions.

In summary, the AOZ8105CI is a unidirectional, fast-acting transient voltage suppressor diode that provides effective protection against overvoltage transients. It has a reverse stand-off voltage of 8V and 400W peak pulse power rating, making it an ideal choice for automotive, industrial, and consumer application as well as for portable electronic systems.
