Product Overview
The SM712 is a surface-mount TVS protection array designed for ESD, EFT, and surge protection on communication and data lines. It uses an asymmetric working-voltage structure with 7V and 12V standoff ratings, making it particularly suitable for differential interfaces such as RS-485. The device supports 400W peak pulse power and 17A peak pulse current under the specified 8/20 µs surge waveform.
Packaged in a compact SOT-23 surface-mount package, the SM712 provides high-level transient protection while maintaining a small PCB footprint. It is suitable for communication ports, industrial interfaces, network protection, wireless systems, and other exposed signal lines requiring combined ESD and surge protection.
