TVS - Diodes are a popular form of protection components used in numerous electronic applications. They are used to limit the current, protect against transient voltage surges, or even protect against harmful electrostatic discharges. The SMP12A-E3/84A is a component specifically designed to provide overvoltage protection from transient voltage spikes due to static electricity or higher than normal line voltages.

This component is able to do so due to its unique and specialized design. The SMP12A-E3/84A is a dual bi-directional TVS diode similar to a zener diode, with two series-connected silicon structures. These two structures help provide a higher level of protection, and are usually linked to an input/output pin in a circuit.

When a voltage surge, electrostatic discharge, or lightning strike occurs, the component will reduce the voltage across it in a short time, and will then quickly turn the voltage to normal levels. This helps to protect the connected circuits from any damage from the surge.

This component is highly popular for use in situations that require high levels of protection. It is most commonly seen in fields such as consumer electronics, automotive metering and monitoring units, industry-level protection circuits, and medical-level protection circuits, where protecting against static electricity and transient voltage spikes is critical.

The working principle of the SMP12A-E3/84A is fairly simple, yet extremely effective. When a voltage surge occurs, the component quickly switches from a low voltage state to a higher voltage state to clamp down the voltage levels, actively reducing the voltage instead of simply passing it on. This helps to provide protection from damage and interruptions in the connected device or system.

The SMP12A-E3/84A also helps to reduce the effect of any electrostatic discharge that may occur, which can be a major cause of system failure in sensitive electronics. This component is designed to quickly detect any static electricity and immediately reduce the voltage to the normal level, again helping to protect any connected circuits from any damage.

Overall, the SMP12A-E3/84A is a highly reliable and efficient way to provide overvoltage protection in sensitive electronics. With its proven effectiveness and ability to rapidly detect and reduce voltage surges, this component has numerous applications in various fields where protection against external disturbances is needed.
