TVS (transient voltage suppressor) diodes are used to protect sensitive electronics from voltage spikes, such as lightning, electrostatic discharge, and other electrical power disturbances. One of the most commonly used TVS diodes is the SMBJ85A-TR, which is a bi-directional device that can handle up to 8.5A of peak pulse current. It can be used in a variety of applications, as it offers fast response times, low levels of leakage current, and excellent voltage clamping characteristics.

The working principle of the SMBJ85A-TR is fairly simple. The diode is designed to act as a barrier to surges in voltage, offering a high breakdown voltage level when normal operating conditions are present. As the voltage rises above the breakdown voltage, the diode becomes conductive, allowing current to flow across it. This causes the voltage to drop, thus providing voltage protection for any downstream components.

The SMBJ85A-TR can be used in a wide range of application fields, including automotive, computers, consumer electronics, telecommunications, and power supplies. It is particularly well-suited for protecting sensitive electronic components, such as microcontrollers and digital signal processors, from voltage spikes due to its fast response time and low leakage current. In addition, it is capable of providing protection in both directions, meaning it can handle spikes from either polarity.

In summary, the SMBJ85A-TR is an ideal choice for protecting sensitive electronics from voltage spikes. It can handle up to 8.5A of peak pulse current, and it offers fast response times, low levels of leakage current, and excellent voltage clamping characteristics. Furthermore, it is suitable for use in a variety of application fields, making it a versatile and reliable protection solution.
