Working Principle

The SA100C-E3/73 operates in the avalanche mode, meaning that it uses a breakdown effect called “avalanche multiplication” to create a fast and powerful response to transients and surges. This mechanism provides the highest levels of protection against high voltage transients in the shortest response time, while generating very low power loss.

When the device is exposed to an over-voltage transient, the diode will quickly and linearly begin to conduct its current with a minimum amount of voltage across it. As the current passes through the diode, it will create an avalanche multiplication effect that results in a rapid rise in voltage across the diode. This avalanche multiplication effect will effectively limit and absorb the energy subjected to the device from the transient, thus protecting the connected device.

Conclusion

The SA100C-E3/73 is an ideal over-voltage and ESD protection component suitable for various digital interface applications. It is capable of providing superior protection across a wide temperature range, and offers fast response time with low power loss. It also features a low clamping voltage and low leakage current, making it an effective solution for protecting sensitive electronics circuits.
