Semtech SM05.TCT TVS Diode ESD Suppressor SOT23

Semtech SM05.TCT is a compact three‑pin TVS diode array in a SOT‑23 package that provides ESD and surge protection for data and transmission lines. It features a 5 V working reverse voltage (VRWM) with a breakdown around 9.8 V, and is rated for up to 150 W peak pulse power (8/20 µs), delivering surge protection while accommodating standard 5 V logic levels. The device guards against electrostatic discharge to IEC 61000‑4‑2 levels of ±15 kV (air) and ±8 kV (contact), and it operates over a temperature range of −55 °C to +125 °C. The SM05.TCT is offered in tape‑and‑reel packaging with a typical base quantity of 3,000 pieces, making it suitable for high‑volume production. Common applications include USB interfaces, microcontroller I/O, sensors, and other high‑speed signal lines where ESD or EFT events may occur.
