AOZ8005FI Circuit Protection

AOZ8005FI is a sub-category of TVS – Diodes which are designed to provide surge protection for electronic components.

AOZ8005FI is an ultra-low capacitance 5-line Transient Voltage Suppression (TVS) diode array used to protect high speed I/O ports from voltage transients generated due to electrostatic discharge (ESD), lightning, inductive load switching, and other transient voltage events. The AOZ8005FI features an ultra-low capacitance of 1.3 pF and provides a maximum ESD voltage protection of ±20 kV per IEC61000-4-2 specification.

This device effectively provides an ultra-low capacitance, ESD protection for high speed digital I/O ports that require ultra-low capacitance solutions. The AOZ8005FI is available in four different voltage ranges (6V, 8V, 12V, 20V) and is offered in industry standard small SOT-23-5 and SOT-25 packages. This device is suitable for applications with high speed protocols, such as USB 2.0, HDMI, and SD cards.

Working Principle

The AOZ8005FI has an ultra-low capacitance of 1.3 pF and can provide ESD protection of ±20 kV per IEC 61000-4-2 specification across its five lines. When the transient voltage exceeds its breakdown level of its designated voltage range, the AOZ8005FI turn off and then switch on again when the voltage falls below its breakdown level. This switching off and on process of the AOZ8005FI is known as surge protection.

The AOZ8005FI also features integrated suppression circuitry, that ensures even during heavy surges, the protection is immediately activated. It also has an internal low power dissipation diode which allows the AOZ8005FI to provide optimum low power protection for a wide range of transient voltage events. The low power dissipation diode also ensures that the device follows the exact ratings of the IEC 61000-4-2 testing conditions.

The combination of the ultra-low capacitance of 1.3 pF across its five lines, and its surge protection capabilities make the AOZ8005FI ideal for use in general and precision applications where ESD is a major concern. This device is ideal for applications such as USB 2.0, HDMI, and SD cards.
