TVS - Diodes

The SMP12A-E3/85A is a transient voltage suppressor diode often used in many electronic applications. It is designed to protect against very brief surges of high voltage, usually from sources such as lightning strikes, electrostatic discharge, and AC coupling. As a unidirectional device, it is able to block voltages higher than its rating and suppress surges much higher than its rating between electrodes.

Overview

The SMP12A-E3/85A is a two-pin device, with an anode and cathode terminal. It is an effective overvoltage protector that is designed to quickly shunt large voltage surges. It features a low-capacitance design that is surge-rated with an excellent holding voltage stability after multiple interface test cycles. With its fast transient response time, it is able to clamp voltages and simplify circuit protection design.

Applications

The SMP12A-E3/85A can be used in various applications, such as digital and/or analog circuit protection in high-voltage, high-current applications, such as communication, computer, and interface circuits. It is also used in displays, drive circuits, and power switching circuits. It can be used to clamp transient voltages in product testing and development.

Technology

When dealing with transient voltage, a diode with a rectifier configuration is used. This consists of a reverse blocking junction, which blocks voltage going in one direction, and a free-wheeling junction, which diverts current away from the parasitic capacitance.

Working Principle

The SMP12A-E3/85A works by shunting the unwanted voltage away from sensitive components. It features an excellent holding voltage stability after multiple interface test cycles, along with a fast transient response time. When excessive and brief surges of voltage are encountered, the SMP12A-E3/85A is able to quickly clamp and shunt the voltage away from sensitive components, thus safeguarding them from damage. Additionally, it offers a low-capacitance design and is surge-rated, which makes it ideal for efficiently blocking high-voltage overshoots.

Conclusion

The SMP12A-E3/85A is a very versatile and popular transient voltage suppressor diode which is widely used to prevent damage from high voltage surges. It is an excellent choice for circuit protection, as it is able to quickly protect high-voltage, high-current applications. With its fast transient response time, high surge rating, and low-capacitance design, the SMP12A-E3/85A is ideal for all types of circuit protection applications.
