TVS - Diodes

3KASMC20AHE3_A/I is a TVS (Transient Voltage Suppressor) diode, also widely used for ESD protection. TVS diodes protect sensitive electrical components from voltage surges, electrostatic discharge (ESD), and other spikes in voltage that can damage circuits. Different products in the same family have different applications as they are designed for different working voltages.

Application Fields

The 3KASMC20AHE3_A/I is designed for use in specialty analog, telecommunications, and low power systems. Its limiting surge capabilities make it ideal for protective applications that require high overload protection and superior surge protection, including automotive, industrial, and communication systems. It is also used in personal computers, digital TV receivers, and high-speed communication equipment.

Working Principle

The TVS diode is a semiconductor device that helps protect critical electronics from voltage surges, electrostatic discharge, and other spikes in voltage. It does so by clamping the voltage across its terminals when the voltage exceeds its rated voltage range. When an over-voltage or surge appears on the circuit, TVS diodes can be used to divert the surge current away from sensitive components, thus protecting the integrity of the system. This works because TVS diodes have a non-linear resistance element, which is located between the cathode and anode. As the voltage across the diode increases, the resistance of the non-linear element decreases, allowing a higher current to flow and then absorbing the excess energy. When the voltage returns to normal levels, the resistance of the non-linear element increases, thus preventing further current flow.

Conclusion

The 3KASMC20AHE3_A/I is a TVS (Transient Voltage Suppressor) diode that is designed for use in specialty analog, telecommunications, and low power systems. It is designed to handle high overload protection and superior surge protection, and can help protect sensitive electronic components from damage caused by voltage surges, electrostatic discharge, and other voltage spikes. Its working principle relies on a non-linear element between its cathode and anode that allows current to flow when the voltage exceeds its rated voltage range, and then reduces the flow of current once the voltage returns to normal levels.
