MALVERN, Pa. — Vishay Intertechnology, Inc. (NYSE: VSH) today introduced four new 100 V Gen 2 Trench MOS Barrier Schottky (TMBS®) rectifier modules in the compact, fully insulated SOT-227 package. Optimized for power conversion in industrial applications, the devices offer best-in-class forward voltage drop down to 0.83 V to reduce conduction losses.
The Vishay Semiconductors rectifier modules released today consist of the dual-diode 100 A VS-QA100FA10, 200 A VS-QA200FA10, and 400 A VS-QA400FA10 in parallel configurations, and the 150 A single phase bridge VS-QA150BA10. With their industry-standard SOT-227 package, the devices can be used as drop-in replacements for competing solutions to increase efficiency.
The modules combine their ultra low forward voltage drop and high current ratings with negligible Qrr and high temperature operation to +150 °C. The devices are intended for high frequency converters and power supplies in welding and industrial SMPS applications, 48 V battery-powered light vehicles, and telecom equipment, and provide blocking diodes for large battery systems.
The VS-QA100FA10, VS-QA150BA10, VS-QA200FA10, and VS-QA400FA10 are RoHS-compliant and UL-approved in accordance with file E78996.
