SM712.TCT TVS Diode – SOT-23-3 – SemTech – RS-485 Protection

Product Description:
The SM712.TCT TVS Diode from SemTech is a high-performance transient voltage suppression device designed specifically for RS-485 and multipoint data transmission systems. It provides asymmetrical protection for +12V and –7V lines, integrating four TVS elements into a compact SOT-23 package—eliminating the need for multiple discrete components.

With a peak pulse power rating of 500–700W (8/20 µs waveform) and a clamping voltage range of 19V to 26V, this device ensures reliable protection against ESD, EFT, and lightning-induced transients. Its low clamping voltage minimizes stress on sensitive transceivers, enhancing system robustness and long-term stability.
