TVS – diodes are electrical components used on printed circuit boards to protect circuits from over-voltage and transients. The SM6S20AHE3/2D is one such device used for advanced surge protection. This three-terminal device has an internal diode which is used to limit the high voltage waveforms, allowing the circuit developers to protect their designs from static electricity, lightning, and other powerful electrical surges. When the voltage exceeds the clamping voltage, the diode fuses and limits the current flow.

The SM6S20AHE3/2D has a 5.7V maximum breakdown voltage and 27pF of capacitance in its anode. This makes it ideal for applications such as noise suppression, electrostatic discharge, or ESD protection for integrated circuits located on printed circuit boards, or PCBs. It is also suitable for general power systems, industrial power systems, and voltage regulation. Its 5.7V maximum breakdown voltage is also low enough to prevent component damage due to a voltage transient.

The SM6S20AHE3/2D\'s working principle is relatively simple. When the voltage across it exceeds the 5.7V clamping voltage, a current will start to flow from the anode to the cathode. This is known as the avalanche current. At this point, the diode will fuse and limit the current to a safe level, protecting the circuit from overvoltage. The device also has an ESD protection type B rating which means it can withstand an ESD shock of up to 8kV.

The SM6S20AHE3/2D also features a low power design, allowing it to be used in a variety of applications. Its low footprint and low cost make it suitable for a wide range of consumer, industrial, and commercial applications. Additionally, its anode has a frequency selection of 50 Hz to 10 kHz, which allows the user to choose the most suitable frequency range for their application.

In summary, the SM6S20AHE3/2D is an advanced surge protection device that is perfect for noise suppression, electrostatic discharge, and ESD protection. It features a 5.7V maximum breakdown voltage, a low power design, a frequency selection of 50 Hz to 10 kHz, and an ESD protection type B rating. With its low footprint and low cost, it is suitable for a wide range of consumer, industrial, and commercial applications.
