The AOZ8211NI-05 is a uni-directional, low capacitance, low clamping voltage (TVS) diode designed to protect High Speed Data and low-voltage Analog and Digital Lines. This device is ideal for protecting sensitive electronics from low energy surges, such as those found in consumer electronics like cell phones, wearable devices, and laptops, as well as industrial and automotive applications.

The AOZ8211NI-05\'s low capacitance and low clamping voltage make it an ideal solution for applications with a need for high data rate transmission, such as HDMI, USB, and Ethernet, as it is capable of protecting against overvoltage/current surges without compromising signal integrity. With a maximum peak pulse current of 75A at 10/1000μs rate, the AOZ8211NI-05 can provide robust protection against overvoltage and overcurrent events.

The AOZ8211NI-05\'s working principle is known as "structure current regulation" or "active overvoltage protection". This type of protection works by monitoring the current flowing through a circuit and using active components to limit the current when the voltage reaches a predetermined level. When triggered, the AOZ8211NI-05 will act as a unidirectional switch, allowing current to flow and protecting the circuit from overvoltage events.

In addition to its overvoltage protection capabilities, the AOZ8211NI-05 also has a wide operating temperature range of up to 150°C. This makes it well-suited to industrial and automotive applications where components must endure extreme temperatures. Additionally, it offers excellent surge and ESD protection with a peak pulse power rating of 8.75W at 8/20μs.

Given its low capacitance and low clamping voltage, the AOZ8211NI-05 is an ideal choice for applications where signal integrity and protection from overvoltage/overcurrent events is needed. This device is well-suited to consumer electronics, industrial, and automotive applications, and provides robust protection against surges and ESD.
