TVS diodes are an important component in the field of electronic engineering. They are used to protect sensitive electronic circuits from overvoltage and other potentially damaging effects. The SMPC26A-M3/87A is a type of TVS diode, specifically designed for the automotive industry. It is a low capacitance, bidirectional, transient voltage suppression diode with a maximum peak pulse power rating of 26A. In this article, we will explain the application field of the SMPC26A-M3/87A and its working principle.

The application field of the SMPC26A-M3/87A includes a variety of automotive electronic systems. It is a common choice in applications that require fast response times and high peak current handling capabilities. This type of diode is suited for automotive applications such as antilock braking systems, dashboard clocks, and electric power steering systems. It is also able to be used in consumer electronics that require low capacitance suppressions.

The working principle of the SMPC26A-M3/87A is based on the principle of avalanche breakdown. Avalanche breakdown occurs when a diode is subjected to a high reverse bias voltage. The reverse bias voltage causes the electrons to be accelerated in the direction of the junction formed between the diode’s semiconductor layers. When the electrons collide with the junction, they create electron-hole pairs which produce additional charge carriers that cause further collisions and potential breakdown of the diode.

The current flowing through the diode is limited by the diode’s avalanche breakdown voltage. When the diode is subjected to a higher voltage, the current is stopped and the voltage is reduced back to its original level. This action provides the diode with protection against high levels of voltage surges.

The peak pulse power rating of a diode is an important factor when determining its ability to handle high levels of voltage. The SMPC26A-M3/87A has a maximum peak pulse power rating of 26A, which is higher than most other types of diode available. This allows the SMPC26A-M3/87A to provide superior protection in applications that require high levels of protection against voltage surges.

The SMPC26A-M3/87A is a type of TVS diode that has been specifically developed for applications in the automotive industry. Its high peak pulse power rating makes it an ideal choice for protecting automotive components against over-voltage damage caused by electrical transients. The diode also provides superior low capacitance protection against high voltage transients. By understanding the application field and working principle of the SMPC26A-M3/87A you can make sure you’re choosing the right diode for your electronic system.
