Vishay VS-QA100FA10
High‑efficiency insulated Gen 2 Schottky rectifier module delivering low losses and robust performance in industrial power‑conversion systems
The VS‑QA100FA10 is a high‑performance insulated Gen 2 Schottky rectifier module designed by Vishay for demanding industrial power‑conversion applications. Built with Trench MOS Barrier Schottky (TMBS®) technology, it integrates two fully independent 100V / 50A diodes in a compact, fully insulated SOT‑227 (miniBLOC) package. This advanced construction delivers ultra‑low forward voltage drop—as low as 0.83 according to Vishay's Gen 2 TMBS product description. Engineered for reliability, the module supports operation up to 150°C junction temperature, ensuring robust performance in harsh environments. Its fast recovery characteristics and low reverse leakage make it well‑suited for high‑frequency converters, welding power supplies, 48V battery‑powered equipment.
