Devices Offer Drop-in Replacements to Reduce Conduction Losses and Increase Efficiency in Industrial Applications
MALVERN, Pa., Jan. 21, 2026 (GLOBE NEWSWIRE) -- 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.
Device Specification Table:
| Part # | IF(AV) / IO (A) | VR / VRRM (V) | VFM (V) | Configuration |
| VS-QA100FA10 | 100 per module | 100 | 0.83 | Two separate diodes, parallel |
| VS-QA150BA10 | 150 | 100 | 0.87 | Single phase bridge |
| VS-QA200FA10 | 200 per module | 100 | 0.83 | Two separate diodes, parallel |
| VS-QA400FA10 | 400 per module | 100 | 0.87 | Two separate diodes, parallel |
