This document describes the features and characteristics of Transient Voltage Suppressors (TVSs). They are used for protecting sensitive components requiring low clamping voltage levels. They can handle high current impulses typically generated by inductive switching transients. Additionally, they have a low-flat profile, providing easier insertion or automatic handling benefits compared to other MELF style packages.
These surface‑mount transient voltage suppressors (TVSs) protect sensitive components by clamping low‑voltage transients. They feature low‑profile J‑bend or gull‑wing terminals for easy placement and stress relief, making them suitable for airborne, satellite, and high‑reliability applications.
The document provides electrical characteristics such as standoff voltage, peak pulse power, and thermal resistance, as well as mechanical data including package dimensions, weight, and UL94V‑0 compliance. Detailed tables list voltage and current ratings for each part number in the SMCG and SMCJ series.
