Transient voltage suppressors (TVS) diodes are a type of semiconductor protection device designed to protect sensitive circuits from transients caused by electrostatic discharge (ESD), lightning, and inductive loads. The 1N8168US is a unidirectional TVS diode that has been widely used in various applications. This paper will discuss the application field and working principle of the 1N8168US TVS diode.

The 1N8168US is a unidirectional TVS diode with an ultra-small package size of 0.6 x 0.4mm, making it a great choice for space-restricted applications. It has an operating temperature range between -40°C to +125°C and is rated for a maximum power dissipation of 100mW and breakdown voltage of 8V. This device has a low capacitance, and its high peak power and ESD ratings make it suitable for a wide range of applications, such as protection of controllers, USB3.0, HDMI, and MIPI. The 1N8168US is also suitable for Lightning protection and load switching.

To understand the working principle of the 1N8168US, we must first understand how a general TVS diode works. Whenever a high voltage transient is applied, the TVS diode will start to conduct current, thereby conducting the transient voltage to a ground potential and limiting the differential voltage. The breakdown voltage of the device refers to the voltage at which the diode starts to conduct current. The 1N8168US’s breakdown voltage is 8V, meaning that it will start to conduct current when the voltage differential between its terminals exceeds 8V.

When a high voltage transient is applied, the TVS diode will start to conduct current and is able to absorb a surge of energy up to its rated peak power. After the transient, the diode will return to a non-conductive state. This is because the peak power of the device is reached when the diode starts to conduct current, and the diode was thus able to limit the differential voltage. This is how the 1N8168US TVS diode works to protect the sensitive circuit from high voltage transients.

In short, the 1N8168US is a unidirectional TVS diode that can be used to protect sensitive circuits from high voltage transients. This device is suitable for a wide range of applications, including but not limited to USB3.0, HDMI, and MIPI. Its ultra-small package size and high peak power and ESD ratings make it a great choice for space-restricted applications. The 1N8168US has a breakdown voltage of 8V and its working principle is that when a high voltage transient is applied, the diode will start to conduct current, thereby absorbing the surge of energy and limiting the differential voltage.
