Additional Details

The SN6400G SIDACtor® is a solid-state device that provides bidirectional overvoltage protection. It is designed to switch to a low-voltage on-state when the voltage exceeds its breakover voltage. The device remains in the on-state until the current falls below its holding current. Proper PCB layout techniques are crucial for minimizing parasitic inductance and ensuring optimal surge protection performance. The SIDACtor should be placed close to the point of entry of the transient surge.

The datasheet provides detailed information regarding the device's electrical characteristics, surge current ratings, and clamping voltage. Consult the datasheet for specific application guidelines and recommended circuit configurations. The device is designed to be robust, but ESD precautions should be observed during handling and installation. The case temperature should be monitored to ensure it remains within the specified operating range.
