TVS-Diodes are a well-known form of protection devices for electronic components or systems. They are also commonly used in myriad applications in both industrial and consumer applications. With the increasing usage of electronic devices, the need for TVS-Diodes has become apparent, and as such a vast array of products are available in the market to suit various budgets and applications. In this article, we will focus on the 5KP100A-G series application field and working principle.

The 5KP100A-G series products are developed by Littelfuse - a leading supplier of quality TVS-Diodes. This series features high surge current ratings and low capacitance which makes it suitable for many applications such as automotive and power supplies. This series includes Diodes 5KP100A-G (300 Watt), 5KP120A-G (500 Watt), and 5KP150A-G (1000 Watts). These products have a maximum peak pulse current of 4500A and a low reverse leakage current of 0.01mA.

The application field of the 5KP100A-G devices covers a variety of use cases such as automotive applications, portable electronics, data communication systems, industrial and power supply circuits. These devices are designed to protect against transients caused by ESD or electrostatic discharges, electrical overstress, overvoltage, and other surge conditions. These devices can also be used to protect against power surges caused by lightning.

The working principle of the 5KP100A-G series devices is based on the avalanche breakdown mechanism, commonly known as spark gap. In simple terms, this means that when an electric current passes through the diode, it will encounter a resistance and the diode will break down due to the voltage applied. The breakdown in the diode will then cause an avalanche effect, which will result in a short burst of current, which can be used to dissipate the voltage. This process also works for reverse voltage, protecting the device from harmful over-voltage conditions.

The process of avalanche breakdown is quite remarkable in that it can take place quickly and safely, effectively dissipating the excess energy that could otherwise cause damage to the electronic components. This process is useful for protecting against the wide variety of electrical surges that can occur in an electronic system. The 5KP100A-G series Diodes can also be used to protect against low to moderate voltage transients such as those from a line fault or short circuit.

Overall, the 5KP100A-G series products are suitable for a broad range of applications and offer reliable and cost-effective protection for sensitive electronic components and systems. The working principle of avalanche breakdown provides reliable protection against a wide variety of electrical surge and over-voltage conditions, making it an ideal choice for applications exposed to such threats.
