TVS - Diodes

 SA12A-E3/73 Application Field and Working Principle

SA12A-E3/73 TVS Devices are unidirectional ESD protection diodes designed for circuit protection against electrostatic discharge (ESD) spikes. These products respond quickly and protect ESD levels up to 20 kV (IEC 801-2) on contact and 30 kV (IEC 801-2) on air discharges. SA12A-E3/73 TVS Diodes are ideally suited for ESD protection on analogue and digital lines and data packs found in consumer grade I/O ports on laptops, mobile phones, portable devices, DVD players, digital cameras, and other consumer digital devices.

SA12A-E3/73 TVS Diodes are based on a unique, patented technology - Ultra Fast Recovery - that achieves both ultra low clamping voltage and very low leakage currents under normal operation. This technology provides industry leading ESD performance, significantly outperforming silicon diodes and other technologies.

SA12A-E3/73 TVS Diodes are available in three different breakdown voltages to match the specific requirements of various applications. They are also available in an 8-pin surface mount package. This package ensures high levels of reliability in harsh environments and requires minimal board space.

The working principle of SA12A-E3/73 protection devices is based on the Ultra Fast Recovery Technology. When exposed to high electrostatic voltages, the device quickly starts to conduct current away from the application device. The device then clamps the voltage at a pre-set level, preventing ESD voltages from increasing or causing damage. Under normal operating conditions, SA12A-E3/73 devices have low leakage currents that will not affect the performance of the application device.

The SA12A-E3/73 TVS Diodes are designed for use in a wide variety of applications including consumer electronics, portable devices, and internet-of-things applications. They are designed to meet the stringent protection requirements of SWAVE C and IEC 801-2 standards. These products provide industry leading ESD protection and superior performance in harsh environments.

In summary, SA12A-E3/73 TVS Diodes are a unique and reliable solution for providing circuit protection against electrostatic discharge (ESD) spikes. They are based on a patented Ultra Fast Recovery Technology that provides ultra low clamping voltage and very low leakage currents. This technology enables the device to protect ESD levels up to 20 kV (IEC 801-2) on contact and 30 kV (IEC 801-2) on air discharges.
