Transient Voltage Suppression (TVS) diodes are designed with the purpose of protecting electrical circuits from overvoltage transients such as electrostatic discharge (ESD). The AOZ8903CI is a uni-directional TVS diode from Diodes Incorporated that is designed to protect sensitive components from ESD strikes and other electrical transients. This device has a low profile, 2.0 mm x 2.0 mm package and is rated for a maximum operating temperature of 150 degrees Celsius. In this article, we\'ll discuss the application field and working principle of the AOZ8903CI TVS diode.

The AOZ8903CI provides protection from ESD events up to 15kV (Human Body Model) and 8kV (Machine Model). It also has a maximum peak pulse power of 8.0 W. It is suitable for use in consumer electronic devices and automotive electronics applications. It has a very low ESD clamping voltage of 6.3V and can support up to 7.0A of continuous current. This device also has very low leakage current and a low parasitic capacitance of only 1.2pF.

The device is designed to protect various components in an electronics circuit from Electrostatic Discharge pulses. It does this by rapidly redirecting transient current away from the components to ground. In order to do this efficiently, the AOZ8903CI utilizes reverse conduction, which is the biasing of the diode when a voltage in excess of the reverse breakdown voltage is applied to the device. This causes the diode to become forward biased and the voltage drop across it decreases significantly. This results in a very low clamping voltage, and the transient current is rapidly redirected away from the components and to ground.

The AOZ8903CI is also able to suppress overvoltage transients, like EMI pulses, which are generated by switching power supplies in consumer electronic devices. When an EMI pulse is applied to the device, it is quickly bypassed to ground through the internal high frequency capacitance. This prevents the components in the circuits from experiencing overvoltage transients, resulting in improved reliability.

In conclusion, the AOZ8903CI is a unidirectional TVS diode from Diodes Incorporated. It is designed to protect sensitive electronic components from electrostatic discharge (ESD) and overvoltage transients, such as EMI pulses. It utilizes reverse conduction to achieve a very low clamping voltage, and its small footprint makes it suitable for use in consumer and automotive electronics applications.
